4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Guoqing Jiang <gqji...@suse.com>
[ Upstream commit 385f4d7f946b08f36f68b0a28e95a319925b6b62 ]
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".
Fixes: 589a1c4 ("Suspend writes in RAID1 if within range")
