[PATCH 1/2] libsas: Don't process sas events in static works

sas devices, but LLDD driver expect libsas add the sas port and devices(last sas event). This patch remove the static defined hotplug work, and use dynamic work to avoid missing hotplug events. Signed-off-by: Yijing Wang Signed-off-by: Yousong He Signed-off-by: Qilin Chen --- drivers/scsi/libsa

[PATCH 2/2] libsas: Enhance libsas hotplug

ait-complete to achieve a sas event atomic process and use latter to make a sas discovery sync. 4. remove disco_mutex in sas_revalidate_domain, since now sas_revalidate_domain sync the destruct discovery event execution, it's no need to lock disco mutex there. Signed-off-by: Yijing Wan

[PATCH v3 4/7] libsas: add sas event wait-complete support

Introduce wait-complete for libsas sas event processing, execute sas port create/destruct in sync. Signed-off-by: Yijing Wang CC: John Garry CC: Johannes Thumshirn CC: Ewan Milne CC: Christoph Hellwig CC: Tomas Henzl CC: Dan Williams --- drivers/scsi/libsas/sas_discover.c | 41

[PATCH v3 1/7] libsas: Use static sas event pool to appease sas event lost

ly, libsas delete the related sas port and sas devices, but LLDD driver expect libsas add the sas port and devices(last sas event). This patch and use static sas event work pool to appease this issue, since it's static work pool, it won't make memory exhaust. Signed-off-by: Yijing Wan

[PATCH v3 6/7] libsas: add wait-complete support to sync discovery event

Introduce a sync flag to tag discovery event whether need to sync execute, per-event wait-complete ensure sync. Signed-off-by: Yijing Wang CC: John Garry CC: Johannes Thumshirn CC: Ewan Milne CC: Christoph Hellwig CC: Tomas Henzl CC: Dan Williams --- drivers/scsi/libsas/sas_discover.c

[PATCH v3 0/7] Enhance libsas hotplug feature

es would occur. The first patch fix the sas events lost, and the second one introudce wait-complete to fix the hotplug order issues. v2->v3: some code improvements suggested by Johannes and John, split v2 patch 2 into several small pathes. v1->v2: some code improvements suggest

[PATCH v3 7/7] libsas: release disco mutex during waiting in sas_ex_discover_end_dev

revalidata domain happen during ata error handler, it should be safe to release disco mutex when sync probe, because no new revalidate domain event would be process until the sync return, and the current sas revalidate domain finish.

[PATCH v3 5/7] libsas: add a new workqueue to run probe/destruct discovery event

Sometimes, we want sync libsas probe or destruct in sas discovery work, like when libsas revalidate domain. We need to split probe and destruct work from the scsi host workqueue. Signed-off-by: Yijing Wang CC: John Garry CC: Johannes Thumshirn CC: Ewan Milne CC: Christoph Hellwig CC: Tomas

[PATCH v3 2/7] libsas: remove unused port_gone_completion

No one uses the port_gone_completion in struct asd_sas_port, clean it out. Signed-off-by: Yijing Wang --- include/scsi/libsas.h | 2 -- 1 file changed, 2 deletions(-) diff --git a/include/scsi/libsas.h b/include/scsi/libsas.h index c41328d..628f48b 100644 --- a/include/scsi/libsas.h +++ b

[PATCH v3 3/7] libsas: Use new workqueue to run sas event

, it may interrupt by other sas event works, like PHYE_LOSS_OF_SIGNAL. Finally, we would found lots unexpected errors. This patch is preparation of execute libsas sas event in sync. Signed-off-by: Yijing Wang CC: John Garry CC: Johannes Thumshirn CC: Ewan Milne CC: Christoph Hellwig CC: Tomas
