Merge tag 'for-5.15/io_uring-2021-09-04' of git://git.kernel.dk/linux-block
Pull io_uring fixes from Jens Axboe:
"As sometimes happens, two reports came in around the merge window open
that led to some fixes. Hence this one is a bit bigger than usual
followup fixes, but most of it will be going towards stable, outside
of the fixes that are addressing regressions from this merge window.
In detail:
- postgres is a heavy user of signals between tasks, and if we're
unlucky this can interfere with io-wq worker creation. Make sure
we're resilient against unrelated signal handling. This set of
changes also includes hardening against allocation failures, which
could previously had led to stalls.
- Some use cases that end up having a mix of bounded and unbounded
work would have starvation issues related to that. Split the
pending work lists to handle that better.
- Completion trace int -> unsigned -> long fix
- Fix issue with REGISTER_IOWQ_MAX_WORKERS and SQPOLL
- Fix regression with hash wait lock in this merge window
- Fix retry issued on block devices (Ming)
- Fix regression with links in this merge window (Pavel)
- Fix race with multi-shot poll and completions (Xiaoguang)
- Ensure regular file IO doesn't inadvertently skip completion
batching (Pavel)
- Ensure submissions are flushed after running task_work (Pavel)"
