From 78d9d7c2a331fb7a68a86e53ef7e12966459e0c5 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Thu, 25 Mar 2021 18:32:45 +0000 Subject: io_uring: don't cancel extra on files match As tasks always wait and kill their io-wq on exec/exit, files are of no more concern to us, so we don't need to specifically cancel them by hand in those cases. Moreover we should not, because io_match_task() looks at req->task->files now, which is always true and so leads to extra cancellations, that wasn't a case before per-task io-wq.
