Pull io_uring fixes from Jens Axboe:
"This one looks a bit bigger than it is, but that's mainly because 2/3
of it is enabling IORING_OP_CLOSE to close direct file descriptors.
We've had a few folks using them and finding it confusing that the way
to close them is through using -1 for file update, this just brings
API symmetry for direct descriptors. Hence I think we should just do
this now and have a better API for 5.15 release. There's some room for
de-duplicating the close code, but we're leaving that for the next
merge window.
Outside of that, just small fixes:
- Poll race fixes (Hao)
- io-wq core dump exit fix (me)
- Reschedule around potentially intensive tctx and buffer iterators
on teardown (me)
- Fix for always ending up punting files update to io-wq (me)
- Put the provided buffer meta data under memcg accounting (me)
- Tweak for io_write(), removing dead code that was added with the
iterator changes in this release (Pavel)"
