Pavel Begunkov	0def123f12	io_uring: break out of iowq iopoll on teardown ... [ upstream commit 45500dc4e01c167ee063f3dcc22f51ced5b2b1e9 ] io-wq will retry iopoll even when it failed with -EAGAIN. If that races with task exit, which sets TIF_NOTIFY_SIGNAL for all its workers, such workers might potentially infinitely spin retrying iopoll again and again and each time failing on some allocation / waiting / etc. Don't keep spinning if io-wq is dying.

Jens Axboe	f435c66d23	io_uring: move to separate directory ... [ Upstream commit ed29b0b4fd835b058ddd151c49d021e28d631ee6 ] In preparation for splitting io_uring up a bit, move it into its own top level directory. It didn't really belong in fs/ anyway, as it's not a file system only API. This adds io_uring/ and moves the core files in there, and updates the MAINTAINERS file for the new location.
