Subject: [PATCH 5.12 0/2] fix sqpoll cancellation hangs
Date: Mon, 15 Mar 2021 14:23:06 +0000 [thread overview]
Message-ID: <[email protected]> (raw)
1/2 is a prep, 2/2 fixes the issue. Many io_run_task_work_head()
call sites look nasty, but I expect them all but one to go away
after controlling SQPOLL task lifetime.
Pavel Begunkov (2):
io_uring: add generic callback_head helpers
io_uring: fix sqpoll cancellation via task_work
