Subject: io_uring: always progress task_work on task cancel
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=55583d72e2303638d30dd4a7aabef59ffa0a017a;p=uclinux-h8%2Flinux.git

io_uring: always progress task_work on task cancel

Might happen that __io_uring_cancel_task_requests() cancels nothing but
there are task_works pending. We need to always run them.
