Hi Linus,
Nothing major in this release, just a bunch of cleanups and some
optimizations around networking mostly.
Will throw a minor conflict in io_uring/net.c due to the late fixes in
mainline, you'll want to keep the kmsg->msg.msg_inq = -1U; assignment
there.
Please pull!
- Series cleaning up file request flags handling (Christoph)
- Series cleaning up request freeing and CQ locking (Pavel)
- Support for using pre-registering the io_uring fd at setup time (Josh)
- Add support for user allocated ring memory, rather than having the
kernel allocate it. Mostly for packing rings into a huge page (me)
- Series avoiding an unnecessary double retry on receive (me)
- Maintain ordering for task_work, which also improves performance (me)
- Misc cleanups/fixes (Pavel, me)
