[PATCH v4 00/19] Replace PCI pool by DMA pool API
The current PCI pool API are simple macro functions direct expanded to the appropriated dma pool functions. The prototypes are almost the same and semantically, they are very similar. I propose to use the DMA pool API directly and get rid of the old API. This set of patches, replaces the old API by the dma pool API, adds support to warn about this old API in checkpath.pl and remove the defines. Changes in v4: - Rebased series onto next-20170301 - Removed patch 20/20: checks done by checkpath.pl, no longer required. Thanks to Peter and Joe for their feedbacks. - Added Reviewed-by tags Changes in v3: - Rebased series onto next-20170224 - Fix checkpath.pl reports for patch 11/20 and patch 12/20 - Remove prefix RFC Changes in v2: - Introduced patch 18/20 - Fixed cosmetic changes: spaces before brace, live over 80 characters - Removed some of the check for NULL pointers before calling dma_pool_destroy - Improved the regexp in checkpatch for pci_pool, thanks to Joe Perches - Added Tested-by and Acked-by tags Romain Perier (19): block: DAC960: Replace PCI pool old API dmaengine: pch_dma: Replace PCI pool old API IB/mthca: Replace PCI pool old API net: e100: Replace PCI pool old API mlx4: Replace PCI pool old API mlx5: Replace PCI pool old API wireless: ipw2200: Replace PCI pool old API scsi: be2iscsi: Replace PCI pool old API scsi: csiostor: Replace PCI pool old API scsi: lpfc: Replace PCI pool old API scsi: megaraid: Replace PCI pool old API scsi: mpt3sas: Replace PCI pool old API scsi: mvsas: Replace PCI pool old API scsi: pmcraid: Replace PCI pool old API usb: gadget: amd5536udc: Replace PCI pool old API usb: gadget: net2280: Replace PCI pool old API usb: gadget: pch_udc: Replace PCI pool old API usb: host: Remove remaining pci_pool in comments PCI: Remove PCI pool macro functions drivers/block/DAC960.c| 36 - drivers/block/DAC960.h| 4 +- drivers/dma/pch_dma.c | 12 +-- drivers/infiniband/hw/mthca/mthca_av.c| 10 +-- drivers/infiniband/hw/mthca/mthca_cmd.c | 8 +- drivers/infiniband/hw/mthca/mthca_dev.h | 4 +- drivers/net/ethernet/intel/e100.c | 12 +-- drivers/net/ethernet/mellanox/mlx4/cmd.c | 10 +-- drivers/net/ethernet/mellanox/mlx4/mlx4.h | 2 +- drivers/net/ethernet/mellanox/mlx5/core/cmd.c | 11 +-- drivers/net/wireless/intel/ipw2x00/ipw2200.c | 13 ++-- drivers/scsi/be2iscsi/be_iscsi.c | 6 +- drivers/scsi/be2iscsi/be_main.c | 6 +- drivers/scsi/be2iscsi/be_main.h | 2 +- drivers/scsi/csiostor/csio_hw.h | 2 +- drivers/scsi/csiostor/csio_init.c | 11 +-- drivers/scsi/csiostor/csio_scsi.c | 6 +- drivers/scsi/lpfc/lpfc.h | 12 +-- drivers/scsi/lpfc/lpfc_init.c | 16 ++-- drivers/scsi/lpfc/lpfc_mem.c | 105 +- drivers/scsi/lpfc/lpfc_nvme.c | 6 +- drivers/scsi/lpfc/lpfc_nvmet.c| 4 +- drivers/scsi/lpfc/lpfc_scsi.c | 12 +-- drivers/scsi/megaraid/megaraid_mbox.c | 33 drivers/scsi/megaraid/megaraid_mm.c | 32 drivers/scsi/megaraid/megaraid_sas_base.c | 29 +++ drivers/scsi/megaraid/megaraid_sas_fusion.c | 66 drivers/scsi/mpt3sas/mpt3sas_base.c | 73 +- drivers/scsi/mvsas/mv_init.c | 6 +- drivers/scsi/mvsas/mv_sas.c | 6 +- drivers/scsi/pmcraid.c| 10 +-- drivers/scsi/pmcraid.h| 2 +- drivers/usb/gadget/udc/amd5536udc.c | 8 +- drivers/usb/gadget/udc/amd5536udc.h | 4 +- drivers/usb/gadget/udc/net2280.c | 12 +-- drivers/usb/gadget/udc/net2280.h | 2 +- drivers/usb/gadget/udc/pch_udc.c | 31 drivers/usb/host/ehci-hcd.c | 2 +- drivers/usb/host/fotg210-hcd.c| 2 +- drivers/usb/host/oxu210hp-hcd.c | 2 +- include/linux/mlx5/driver.h | 2 +- include/linux/pci.h | 9 --- 42 files changed, 310 insertions(+), 331 deletions(-) -- 2.9.3

Changes in v10: - Rebased series onto next-20170706 - I have fixed and improved patch "scsi: megaraid: Replace PCI pool old API" Changes in v9: - Rebased series onto next-20170522 - I have fixed and improved the patch for lpfc driver Changes in v8: - Rebased series onto next-20170428 Changes in v7: - Rebased series onto next-20170416 - Added Acked-by, Tested-by and Reviwed-by tags Changes in v6: - Fixed an issue reported by kbuild test robot about changes in DAC960 - Removed patches 15/19,16/19,17/19,18/19. They have been merged by Greg - Added Acked-by Tags Changes in v5: - Re-worded the cover letter (remove sentence about checkpatch.pl) - Rebased series onto next-20170308 - Fix typos in commit message - Added Acked-by Tags Changes in v4: - Rebased series onto next-20170301 - Removed patch 20/20: checks done by checkpath.pl, no longer required. Thanks to Peter and Joe for their feedbacks. - Added Reviewed-by tags Changes in v3: - Rebased series onto next-20170224 - Fix checkpath.pl reports for patch 11/20 and patch 12/20 - Remove prefix RFC Changes in v2: - Introduced patch 18/20 - Fixed cosmetic changes: spaces before brace, live over 80 characters - Removed some of the check for NULL pointers before calling dma_pool_destroy - Improved the regexp in checkpatch for pci_pool, thanks to Joe Perches - Added Tested-by and Acked-by tags Romain Perier (15): block: DAC960: Replace PCI pool old API dmaengine: pch_dma: Replace PCI pool old API IB/mthca: Replace PCI pool old API net: e100: Replace PCI pool old API mlx4: Replace PCI pool old API mlx5: Replace PCI pool old API wireless: ipw2200: Replace PCI pool old API scsi: be2iscsi: Replace PCI pool old API scsi: csiostor: Replace PCI pool old API scsi: lpfc: Replace PCI pool old API scsi: megaraid: Replace PCI pool old API scsi: mpt3sas: Replace PCI pool old API scsi: mvsas: Replace PCI pool old API scsi: pmcraid: Replace PCI pool old API PCI: Remove PCI pool macro functions drivers/block/DAC960.c| 38 ++- drivers/block/DAC960.h| 4 +- drivers/dma/pch_dma.c | 12 ++-- drivers/infiniband/hw/mthca/mthca_av.c| 10 +-- drivers/infiniband/hw/mthca/mthca_cmd.c | 8 +-- drivers/infiniband/hw/mthca/mthca_dev.h | 4 +- drivers/net/ethernet/intel/e100.c | 12 ++-- drivers/net/ethernet/mellanox/mlx4/cmd.c | 10 +-- drivers/net/ethernet/mellanox/mlx4/mlx4.h | 2 +- drivers/net/ethernet/mellanox/mlx5/core/cmd.c | 11 ++-- drivers/net/wireless/intel/ipw2x00/ipw2200.c | 13 ++-- drivers/scsi/be2iscsi/be_iscsi.c | 6 +- drivers/scsi/be2iscsi/be_main.c | 6 +- drivers/scsi/be2iscsi/be_main.h | 2 +- drivers/scsi/csiostor/csio_hw.h | 2 +- drivers/scsi/csiostor/csio_init.c | 11 ++-- drivers/scsi/csiostor/csio_scsi.c | 6 +- drivers/scsi/lpfc/lpfc.h | 16 ++--- drivers/scsi/lpfc/lpfc_init.c | 16 ++--- drivers/scsi/lpfc/lpfc_mem.c | 90 +-- drivers/scsi/lpfc/lpfc_nvme.c | 6 +- drivers/scsi/lpfc/lpfc_nvmet.c| 4 +- drivers/scsi/lpfc/lpfc_scsi.c | 12 ++-- drivers/scsi/lpfc/lpfc_sli.c | 6 +- drivers/scsi/megaraid/megaraid_mbox.c | 30 - drivers/scsi/megaraid/megaraid_mm.c | 29 - drivers/scsi/megaraid/megaraid_sas_base.c | 27 drivers/scsi/megaraid/megaraid_sas_fusion.c | 46 +++--- drivers/scsi/mpt3sas/mpt3sas_base.c | 73 ++ drivers/scsi/mvsas/mv_init.c | 6 +- drivers/scsi/mvsas/mv_sas.c | 6 +- drivers/scsi/pmcraid.c| 10 +-- drivers/scsi/pmcraid.h| 2 +- include/linux/mlx5/driver.h | 2 +- include/linux/pci.h | 9 --- 35 files changed, 269 insertions(+), 278 deletions(-) -- 2.11.0

[PATCH v5 00/19] Replace PCI pool by DMA pool API
The current PCI pool API are simple macro functions direct expanded to the appropriate dma pool functions. The prototypes are almost the same and semantically, they are very similar. I propose to use the DMA pool API directly and get rid of the old API. This set of patches, replaces the old API by the dma pool API and remove the defines. Changes in v5: - Re-worded the cover letter (remove sentence about checkpatch.pl) - Rebased series onto next-20170308 - Fix typos in commit message - Added Acked-by Tags Changes in v4: - Rebased series onto next-20170301 - Removed patch 20/20: checks done by checkpath.pl, no longer required. Thanks to Peter and Joe for their feedbacks. - Added Reviewed-by tags Changes in v3: - Rebased series onto next-20170224 - Fix checkpath.pl reports for patch 11/20 and patch 12/20 - Remove prefix RFC Changes in v2: - Introduced patch 18/20 - Fixed cosmetic changes: spaces before brace, live over 80 characters - Removed some of the check for NULL pointers before calling dma_pool_destroy - Improved the regexp in checkpatch for pci_pool, thanks to Joe Perches - Added Tested-by and Acked-by tags Romain Perier (19): block: DAC960: Replace PCI pool old API dmaengine: pch_dma: Replace PCI pool old API IB/mthca: Replace PCI pool old API net: e100: Replace PCI pool old API mlx4: Replace PCI pool old API mlx5: Replace PCI pool old API wireless: ipw2200: Replace PCI pool old API scsi: be2iscsi: Replace PCI pool old API scsi: csiostor: Replace PCI pool old API scsi: lpfc: Replace PCI pool old API scsi: megaraid: Replace PCI pool old API scsi: mpt3sas: Replace PCI pool old API scsi: mvsas: Replace PCI pool old API scsi: pmcraid: Replace PCI pool old API usb: gadget: amd5536udc: Replace PCI pool old API usb: gadget: net2280: Replace PCI pool old API usb: gadget: pch_udc: Replace PCI pool old API usb: host: Remove remaining pci_pool in comments PCI: Remove PCI pool macro functions drivers/block/DAC960.c| 36 - drivers/block/DAC960.h| 4 +- drivers/dma/pch_dma.c | 12 +-- drivers/infiniband/hw/mthca/mthca_av.c| 10 +-- drivers/infiniband/hw/mthca/mthca_cmd.c | 8 +- drivers/infiniband/hw/mthca/mthca_dev.h | 4 +- drivers/net/ethernet/intel/e100.c | 12 +-- drivers/net/ethernet/mellanox/mlx4/cmd.c | 10 +-- drivers/net/ethernet/mellanox/mlx4/mlx4.h | 2 +- drivers/net/ethernet/mellanox/mlx5/core/cmd.c | 11 +-- drivers/net/wireless/intel/ipw2x00/ipw2200.c | 13 ++-- drivers/scsi/be2iscsi/be_iscsi.c | 6 +- drivers/scsi/be2iscsi/be_main.c | 6 +- drivers/scsi/be2iscsi/be_main.h | 2 +- drivers/scsi/csiostor/csio_hw.h | 2 +- drivers/scsi/csiostor/csio_init.c | 11 +-- drivers/scsi/csiostor/csio_scsi.c | 6 +- drivers/scsi/lpfc/lpfc.h | 14 ++-- drivers/scsi/lpfc/lpfc_init.c | 16 ++-- drivers/scsi/lpfc/lpfc_mem.c | 106 +- drivers/scsi/lpfc/lpfc_nvme.c | 6 +- drivers/scsi/lpfc/lpfc_nvmet.c| 4 +- drivers/scsi/lpfc/lpfc_scsi.c | 12 +-- drivers/scsi/megaraid/megaraid_mbox.c | 33 drivers/scsi/megaraid/megaraid_mm.c | 32 drivers/scsi/megaraid/megaraid_sas_base.c | 29 +++ drivers/scsi/megaraid/megaraid_sas_fusion.c | 66 drivers/scsi/mpt3sas/mpt3sas_base.c | 73 +- drivers/scsi/mvsas/mv_init.c | 6 +- drivers/scsi/mvsas/mv_sas.c | 6 +- drivers/scsi/pmcraid.c| 10 +-- drivers/scsi/pmcraid.h| 2 +- drivers/usb/gadget/udc/amd5536udc.c | 8 +- drivers/usb/gadget/udc/amd5536udc.h | 4 +- drivers/usb/gadget/udc/net2280.c | 12 +-- drivers/usb/gadget/udc/net2280.h | 2 +- drivers/usb/gadget/udc/pch_udc.c | 31 drivers/usb/host/ehci-hcd.c | 2 +- drivers/usb/host/fotg210-hcd.c| 2 +- drivers/usb/host/oxu210hp-hcd.c | 2 +- include/linux/mlx5/driver.h | 2 +- include/linux/pci.h | 9 --- 42 files changed, 311 insertions(+), 333 deletions(-) -- 2.9.3

We cannot test a patch like this one on all affected platforms/drivers (at runtime). Simply because we have not the hw. As Peter said, we tested this by compilation only for now via make allyesconfig. That's up to the maintainer of the subsystem to test and ack this, imho. I agree with Peter, this should not affect runtime (as semantically it's compatible and have been validated statically and semantically by your compiler) Regards, Romain

[PATCH v6 00/15] Replace PCI pool by DMA pool API
The current PCI pool API are simple macro functions direct expanded to the appropriate dma pool functions. The prototypes are almost the same and semantically, they are very similar. I propose to use the DMA pool API directly and get rid of the old API. This set of patches, replaces the old API by the dma pool API and remove the defines. Changes in v6: - Fixed an issue reported by kbuild test robot about changes in DAC960 - Removed patches 15/19,16/19,17/19,18/19. They have been merged by Greg - Added Acked-by Tags Changes in v5: - Re-worded the cover letter (remove sentence about checkpatch.pl) - Rebased series onto next-20170308 - Fix typos in commit message - Added Acked-by Tags Changes in v4: - Rebased series onto next-20170301 - Removed patch 20/20: checks done by checkpath.pl, no longer required. Thanks to Peter and Joe for their feedbacks. - Added Reviewed-by tags Changes in v3: - Rebased series onto next-20170224 - Fix checkpath.pl reports for patch 11/20 and patch 12/20 - Remove prefix RFC Changes in v2: - Introduced patch 18/20 - Fixed cosmetic changes: spaces before brace, live over 80 characters - Removed some of the check for NULL pointers before calling dma_pool_destroy - Improved the regexp in checkpatch for pci_pool, thanks to Joe Perches - Added Tested-by and Acked-by tags Romain Perier (15): block: DAC960: Replace PCI pool old API dmaengine: pch_dma: Replace PCI pool old API IB/mthca: Replace PCI pool old API net: e100: Replace PCI pool old API mlx4: Replace PCI pool old API mlx5: Replace PCI pool old API wireless: ipw2200: Replace PCI pool old API scsi: be2iscsi: Replace PCI pool old API scsi: csiostor: Replace PCI pool old API scsi: lpfc: Replace PCI pool old API scsi: megaraid: Replace PCI pool old API scsi: mpt3sas: Replace PCI pool old API scsi: mvsas: Replace PCI pool old API scsi: pmcraid: Replace PCI pool old API PCI: Remove PCI pool macro functions drivers/block/DAC960.c| 38 + drivers/block/DAC960.h| 4 +- drivers/dma/pch_dma.c | 12 +-- drivers/infiniband/hw/mthca/mthca_av.c| 10 +-- drivers/infiniband/hw/mthca/mthca_cmd.c | 8 +- drivers/infiniband/hw/mthca/mthca_dev.h | 4 +- drivers/net/ethernet/intel/e100.c | 12 +-- drivers/net/ethernet/mellanox/mlx4/cmd.c | 10 +-- drivers/net/ethernet/mellanox/mlx4/mlx4.h | 2 +- drivers/net/ethernet/mellanox/mlx5/core/cmd.c | 11 +-- drivers/net/wireless/intel/ipw2x00/ipw2200.c | 13 ++-- drivers/scsi/be2iscsi/be_iscsi.c | 6 +- drivers/scsi/be2iscsi/be_main.c | 6 +- drivers/scsi/be2iscsi/be_main.h | 2 +- drivers/scsi/csiostor/csio_hw.h | 2 +- drivers/scsi/csiostor/csio_init.c | 11 +-- drivers/scsi/csiostor/csio_scsi.c | 6 +- drivers/scsi/lpfc/lpfc.h | 14 ++-- drivers/scsi/lpfc/lpfc_init.c | 16 ++-- drivers/scsi/lpfc/lpfc_mem.c | 106 +- drivers/scsi/lpfc/lpfc_nvme.c | 6 +- drivers/scsi/lpfc/lpfc_nvmet.c| 4 +- drivers/scsi/lpfc/lpfc_scsi.c | 12 +-- drivers/scsi/megaraid/megaraid_mbox.c | 33 drivers/scsi/megaraid/megaraid_mm.c | 32 drivers/scsi/megaraid/megaraid_sas_base.c | 29 +++ drivers/scsi/megaraid/megaraid_sas_fusion.c | 66 drivers/scsi/mpt3sas/mpt3sas_base.c | 73 +- drivers/scsi/mvsas/mv_init.c | 6 +- drivers/scsi/mvsas/mv_sas.c | 6 +- drivers/scsi/pmcraid.c| 10 +-- drivers/scsi/pmcraid.h| 2 +- include/linux/mlx5/driver.h | 2 +- include/linux/pci.h | 9 --- 34 files changed, 280 insertions(+), 303 deletions(-) -- 2.9.3

[PATCH v7 00/15] Replace PCI pool by DMA pool API
The current PCI pool API are simple macro functions direct expanded to the appropriate dma pool functions. The prototypes are almost the same and semantically, they are very similar. I propose to use the DMA pool API directly and get rid of the old API. This set of patches, replaces the old API by the dma pool API and remove the defines. Changes in v7: - Rebased series onto next-20170416 - Added Acked-by, Tested-by and Reviwed-by tags Changes in v6: - Fixed an issue reported by kbuild test robot about changes in DAC960 - Removed patches 15/19,16/19,17/19,18/19. They have been merged by Greg - Added Acked-by Tags Changes in v5: - Re-worded the cover letter (remove sentence about checkpatch.pl) - Rebased series onto next-20170308 - Fix typos in commit message - Added Acked-by Tags Changes in v4: - Rebased series onto next-20170301 - Removed patch 20/20: checks done by checkpath.pl, no longer required. Thanks to Peter and Joe for their feedbacks. - Added Reviewed-by tags Changes in v3: - Rebased series onto next-20170224 - Fix checkpath.pl reports for patch 11/20 and patch 12/20 - Remove prefix RFC Changes in v2: - Introduced patch 18/20 - Fixed cosmetic changes: spaces before brace, live over 80 characters - Removed some of the check for NULL pointers before calling dma_pool_destroy - Improved the regexp in checkpatch for pci_pool, thanks to Joe Perches - Added Tested-by and Acked-by tags Romain Perier (15): block: DAC960: Replace PCI pool old API dmaengine: pch_dma: Replace PCI pool old API IB/mthca: Replace PCI pool old API net: e100: Replace PCI pool old API mlx4: Replace PCI pool old API mlx5: Replace PCI pool old API wireless: ipw2200: Replace PCI pool old API scsi: be2iscsi: Replace PCI pool old API scsi: csiostor: Replace PCI pool old API scsi: lpfc: Replace PCI pool old API scsi: megaraid: Replace PCI pool old API scsi: mpt3sas: Replace PCI pool old API scsi: mvsas: Replace PCI pool old API scsi: pmcraid: Replace PCI pool old API PCI: Remove PCI pool macro functions drivers/block/DAC960.c| 38 + drivers/block/DAC960.h| 4 +- drivers/dma/pch_dma.c | 12 +-- drivers/infiniband/hw/mthca/mthca_av.c| 10 +-- drivers/infiniband/hw/mthca/mthca_cmd.c | 8 +- drivers/infiniband/hw/mthca/mthca_dev.h | 4 +- drivers/net/ethernet/intel/e100.c | 12 +-- drivers/net/ethernet/mellanox/mlx4/cmd.c | 10 +-- drivers/net/ethernet/mellanox/mlx4/mlx4.h | 2 +- drivers/net/ethernet/mellanox/mlx5/core/cmd.c | 11 +-- drivers/net/wireless/intel/ipw2x00/ipw2200.c | 13 ++-- drivers/scsi/be2iscsi/be_iscsi.c | 6 +- drivers/scsi/be2iscsi/be_main.c | 6 +- drivers/scsi/be2iscsi/be_main.h | 2 +- drivers/scsi/csiostor/csio_hw.h | 2 +- drivers/scsi/csiostor/csio_init.c | 11 +-- drivers/scsi/csiostor/csio_scsi.c | 6 +- drivers/scsi/lpfc/lpfc.h | 14 ++-- drivers/scsi/lpfc/lpfc_init.c | 16 ++-- drivers/scsi/lpfc/lpfc_mem.c | 106 +- drivers/scsi/lpfc/lpfc_nvme.c | 6 +- drivers/scsi/lpfc/lpfc_nvmet.c| 4 +- drivers/scsi/lpfc/lpfc_scsi.c | 12 +-- drivers/scsi/megaraid/megaraid_mbox.c | 33 drivers/scsi/megaraid/megaraid_mm.c | 32 drivers/scsi/megaraid/megaraid_sas_base.c | 29 +++ drivers/scsi/megaraid/megaraid_sas_fusion.c | 66 drivers/scsi/mpt3sas/mpt3sas_base.c | 73 +- drivers/scsi/mvsas/mv_init.c | 6 +- drivers/scsi/mvsas/mv_sas.c | 6 +- drivers/scsi/pmcraid.c| 10 +-- drivers/scsi/pmcraid.h| 2 +- include/linux/mlx5/driver.h | 2 +- include/linux/pci.h | 9 --- 34 files changed, 280 insertions(+), 303 deletions(-) -- 2.9.3
