Merge patch series "poll_wait: add mb() to fix theoretical race between waitqueue_active() and .poll()"
Oleg Nesterov <oleg@redhat.com> says:
The waitqueue_active() helper can only be used if both waker and waiter
have memory barriers that pair with each other. But __pollwait() is
broken in this respect. Fix it.
* patches from https://lore.kernel.org/r/20250107162649.GA18886@redhat.com:
poll: kill poll_does_not_wait()
sock_poll_wait: kill the no longer necessary barrier after poll_wait()
io_uring_poll: kill the no longer necessary barrier after poll_wait()
poll_wait: kill the obsolete wait_address check
poll_wait: add mb() to fix theoretical race between waitqueue_active() and .poll()
