[dm-devel] [PATCH 0/3] block: keep quiesce & unquiesce balanced for scsi/dm

[Ming Lei]

Hello Jens,

Recently we merge the patch of e70feb8b3e68 ("blk-mq: support concurrent queue
quiesce/unquiesce") for fixing race between driver and block layer wrt.
queue quiesce.

Yi reported that srp/002 is broken with this patch, turns out scsi and
dm don't keep the two balanced actually.

So fix dm and scsi and make srp/002 pass again.


Ming Lei (3):
  scsi: avoid to quiesce sdev->request_queue two times
  scsi: make sure that request queue queiesce and unquiesce balanced
  dm: don't stop request queue after the dm device is suspended
