Subject: [PATCHSET REBASE 07/10] io_uring: simplify io_has_work
Date: Thu,  5 Jan 2023 11:22:26 +0000	[thread overview]
Message-ID: <26af9f73c09a56c9a035f94db56127358688f3aa.1672916894.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

->work_llist should never be non-empty for a non DEFER_TASKRUN ring, so
we can safely skip checking the flag.
