From a6d45dd0d43e6d1275e002704540688b6768bc22 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Sat, 27 Jun 2020 14:04:57 +0300 Subject: [PATCH] io_uring: don't mark link's head for_async No reason to mark a head of a link as for-async in io_req_defer_prep(). grab_env(), etc. That will be done further during submission if neccessary. Mark for_async=false saving extra grab_env() in many cases.
