From 385f4d7f946b08f36f68b0a28e95a319925b6b62 Mon Sep 17 00:00:00 2001 From: Guoqing Jiang Date: Fri, 29 Sep 2017 09:16:43 +0800 Subject: md-cluster: fix wrong condition check in raid1_write_request The check used here is to avoid conflict between write and resync, however we used the wrong logic, it should be the inverse of the checking inside "if".
