From 06de5f5973c641c7ae033f133ecfaaf64fe633a6 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Fri, 6 Nov 2020 13:00:21 +0000 Subject: [PATCH] io_uring: simplify io_task_match() If IORING_SETUP_SQPOLL is set all requests belong to the corresponding SQPOLL task, so skip task checking in that case and always match.
