Subject: [PATCH 0/8] ublk: simplify NEED_GET_DATA handling and request lookup
Date: Sat, 26 Apr 2025 22:57:55 -0600 [thread overview]
Message-ID: <20250427045803.772972-1-csander@purestorage.com> (raw)
Remove accesses to ublk_io's cmd field after the I/O request is posted to the
ublk server. This allows the cmd field to be overlapped with a pointer to the
struct request, avoiding several blk_mq_tag_to_rq() lookups.
Fix a couple of typos noticed along the way.
Caleb Sander Mateos (7):
ublk: fix "immepdately" typo in comment
ublk: remove misleading "ubq" in "ubq_complete_io_cmd()"
ublk: don't log uring_cmd cmd_op in ublk_dispatch_req()
ublk: factor out ublk_start_io() helper
ublk: don't call ublk_dispatch_req() for NEED_GET_DATA
ublk: check UBLK_IO_FLAG_OWNED_BY_SRV in ublk_abort_queue()
ublk: store request pointer in ublk_io
Uday Shankar (1):
ublk: factor out ublk_commit_and_fetch
