Subject: [PATCH 0/3] fix nested uring_lock
Date: Thu, 18 Feb 2021 22:32:50 +0000 [thread overview]
Message-ID: <cover.1613687339.git.asml.silence@gmail.com> (raw)
1/3 is for backporting, two others are more churny, but do it right,
including trying to punt it to the original task instead of fallback,
aka io-wq manager.
Pavel Begunkov (3):
io_uring: don't take uring_lock during iowq cancel
io_uring: fail io-wq submission from a task_work
io_uring: avoid taking ctx refs for task-cancel
