From 0c4fe008c9cb2215b3f838769886857ae986014b Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Thu, 5 Jan 2023 11:22:20 +0000 Subject: io_uring: rearrange defer list checks There should be nothing in the ->work_llist for non DEFER_TASKRUN rings, so we can skip flag checks and test the list emptiness directly. Also move it out of io_run_local_work() for inlining.
