Hi Linus,
Sending pull requests early, as I'm mostly out-of-town and unavailable
next week.
Here are the io_uring updates for the 6.3 merge window. Nothing really
major in here for this round. In detail:
- Cleanup series making the async prep and handling of REQ_F_FORCE_ASYNC
easier to follow and verify (Dylan)
- Enable specifying specific flags for OP_MSG_RING (Breno)
- Enable use of KASAN with the internal request cache (Breno)
- Split the opcode definition structs into a hot and cold part (Breno)
- OP_MSG_RING fixes (Pavel, me)
- Fix an issue with IOPOLL cancelation and PREEMPT_NONE (me)
- Handle TIF_NOTIFY_RESUME for the io-wq threads that never return to
userspace (me)
- Add support for using io_uring_register() with a registered ring fd
(Josh)
- Improve handling of poll on the ring fd (Pavel)
- Series improving the task_work handling (Pavel)
- Misc cleanups, fixes, improvements (Dmitrii, Quanfa, Richard, Pavel, me)
Please pull!
