Subject: [PATCHv3 0/4] block and nvme passthrough error handling
Date: Fri, 21 May 2021 13:21:41 -0700 [thread overview]
Message-ID: <20210521202145.3674904-1-kbusch@kernel.org> (raw)
This series gets blk_execute_rq() to process polled requests and return
queueing errors so the caller may know if their request wasn't
dispatched.
Changes since v2:
Dropped patch 5 (ioctl polling flag) since there is currently no real
use case.
Move blk_execute_rq's poll handling to a small helper function
(patch 1)
Return blk_status_t instead of errno (patch 3)
Removed "extern" header declaration, and named the parameters (patch 3)
Initialize nvme status to 0 (patch 4)
Add helper function for blk_status_t to nvme passthrough return code
(patch 4)
Keith Busch (4):
block: support polling through blk_execute_rq
nvme: use blk_execute_rq() for passthrough commands
block: return errors from blk_execute_rq()
nvme: use return value from blk_execute_rq()
