Subject: [RFC PATCH 0/4] cleanup io_put/free
Date: Thu, 21 Nov 2019 23:20:59 +0300 [thread overview]
Message-ID: <cover.1574366549.git.asml.silence@gmail.com> (raw)
Nested checking @nxt for non-nullness in io_put_req_find_next() and
friends is a nuisance. Make them accept only non-null @nxt obliging
callers to io_queue_async_work() if they don't need @nxt.
The patchset is a bit rusty (rebased), but still relevant. The part
removing io_wq_current_is_worker() (PATCH 2/4) looks good, but would
like someone to check the assumption.
P.S. it depends on the patch with renaming __io_submit_sqe().
Pavel Begunkov (4):
io_uring: remove io_free_req_find_next()
io_uring: pass only !null to io_req_find_next()
io_uring: simplify io_req_link_next()
io_uring: only !null ptr to io_issue_sqe()
