From b0dc0883a2051415c4ca5945326aa630254df18f Mon Sep 17 00:00:00 2001 From: Xiaoguang Wang Date: Sun, 28 Jun 2020 20:47:07 +0800 Subject: [PATCH 1578/2944] io_uring: don't fail links for EAGAIN error in IOPOLL mode to #28736503 commit 2d7d67920e5c8e0854df23ca77da2dd5880ce5dd upstream In IOPOLL mode, for EAGAIN error, we'll try to submit io request again using io-wq, so don't fail rest of links if this io request has links.
