Merge tag 'io_uring-5.16-2021-12-10' of git://git.kernel.dk/linux-block
Pull io_uring fixes from Jens Axboe:
"A few fixes that are all bound for stable:
- Two syzbot reports for io-wq that turned out to be separate fixes,
but ultimately very closely related
- io_uring task_work running on cancelations"
* tag 'io_uring-5.16-2021-12-10' of git://git.kernel.dk/linux-block:
io-wq: check for wq exit after adding new worker task_work
io_uring: ensure task_work gets run as part of cancelations
io-wq: remove spurious bit clear on task_work addition
