From 6bb30855560e6343e7b88595d7c3159d0f848a04 Mon Sep 17 00:00:00 2001 From: Dylan Yudaken Date: Fri, 27 Jan 2023 05:52:24 -0800 Subject: [PATCH] io_uring: if a linked request has REQ_F_FORCE_ASYNC then run it async REQ_F_FORCE_ASYNC was being ignored for re-queueing linked requests. Instead obey that flag.
