Merge tag 'for-5.12/io_uring-2021-02-17' of git://git.kernel.dk/linux-block
Pull io_uring updates from Jens Axboe:
"Highlights from this cycles are things like request recycling and
task_work optimizations, which net us anywhere from 10-20% of speedups
on workloads that mostly are inline.
This work was originally done to put io_uring under memcg, which adds
considerable overhead. But it's a really nice win as well. Also worth
highlighting is the LOOKUP_CACHED work in the VFS, and using it in
io_uring. Greatly speeds up the fast path for file opens.
Summary:
- Put io_uring under memcg protection. We accounted just the rings
themselves under rlimit memlock before, now we account everything.
- Request cache recycling, persistent across invocations (Pavel, me)
- First part of a cleanup/improvement to buffer registration (Bijan)
- SQPOLL fixes (Hao)
- File registration NULL pointer fixup (Dan)
- LOOKUP_CACHED support for io_uring
- Disable /proc/thread-self/ for io_uring, like we do for /proc/self
- Add Pavel to the io_uring MAINTAINERS entry
- Tons of code cleanups and optimizations (Pavel)
- Support for skip entries in file registration (Noah)"
