Subject: [PATCHSET v2 0/3] Add io_uring support for epoll_ctl
Date: Wed, 22 Jan 2020 09:42:41 -0700 [thread overview]
Message-ID: <20200122164244.27799-1-axboe@kernel.dk> (raw)
This adds support for epoll manipulation through io_uring, in particular
epoll_ctl(2). Patch 1 is just a prep patch, patch 2 adds non-block
support for epoll, and patch 3 wires it up for io_uring.
Patch 2 isn't the prettiest thing in the world, but we need to do
nonblock grabbing of the mutexes and be able to back out safely.
Please review, thanks.
Since v1:
- Use right version...
- Fix locking in eventpoll
- Don't EINVAL on sqe->off in epoll prep for io_uring
