Subject[PATCH 5.10 01/54] io_uring: simplify io_task_match()
Date
From: Pavel Begunkov <asml.silence@gmail.com>

[ Upstream commit 06de5f5973c641c7ae033f133ecfaaf64fe633a6 ]

If IORING_SETUP_SQPOLL is set all requests belong to the corresponding
SQPOLL task, so skip task checking in that case and always match.
