Follow up patches to 77873803363c "net_dma: mark broken" to remove net_dma bits and provide debug infrastructure to flag other get_user_pages() vs dma instances that might violate the dma api.
Will takes this through the dmaengine tree once acked. Just looking for an ack to patch 2 at this point. Changes since v2 [1]: 1/ Keep the 'tcp_' prefix to cleanup_rbuf() in patch 3 2/ Fix up patch 4 according to Andrew's comments: Added documentation and dropped CONFIG_DMA_VS_CPU_DEBUG. [2] Changes since v1 [3]: 1/ net_dma removal patch has been expanded to revert other net_dma induced changes. 2/ updated the debug_dma_assert_idle() api to be gated on CONFIG_DMA_VS_CPU_DEBUG [1]: http://marc.info/?l=linux-netdev&m=138929837129496&w=2 [2]: http://marc.info/?l=linux-netdev&m=138931431901890&w=2 [3]: http://marc.info/?l=linux-netdev&m=138732574814049&w=2 --- Dan Williams (4): net_dma: simple removal net_dma: revert 'copied_early' net: make tcp_cleanup_rbuf private dma debug: introduce debug_dma_assert_idle() Documentation/ABI/removed/net_dma | 8 + Documentation/networking/ip-sysctl.txt | 6 - drivers/dma/Kconfig | 12 - drivers/dma/Makefile | 1 drivers/dma/dmaengine.c | 104 ------------ drivers/dma/ioat/dma.c | 1 drivers/dma/ioat/dma.h | 7 - drivers/dma/ioat/dma_v2.c | 1 drivers/dma/ioat/dma_v3.c | 1 drivers/dma/iovlock.c | 280 -------------------------------- include/linux/dma-debug.h | 6 + include/linux/dmaengine.h | 22 --- include/linux/skbuff.h | 8 - include/linux/tcp.h | 8 - include/net/netdma.h | 32 ---- include/net/sock.h | 19 -- include/net/tcp.h | 9 - kernel/sysctl_binary.c | 1 lib/Kconfig.debug | 12 + lib/dma-debug.c | 169 ++++++++++++++++++- mm/memory.c | 3 net/core/Makefile | 1 net/core/dev.c | 10 - net/core/sock.c | 6 - net/core/user_dma.c | 131 --------------- net/dccp/proto.c | 4 net/ipv4/sysctl_net_ipv4.c | 9 - net/ipv4/tcp.c | 149 ++--------------- net/ipv4/tcp_input.c | 83 +-------- net/ipv4/tcp_ipv4.c | 18 -- net/ipv6/tcp_ipv6.c | 13 - net/llc/af_llc.c | 10 + 32 files changed, 219 insertions(+), 925 deletions(-) create mode 100644 Documentation/ABI/removed/net_dma delete mode 100644 drivers/dma/iovlock.c delete mode 100644 include/net/netdma.h delete mode 100644 net/core/user_dma.c -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
