From 68515cc72191f5c5d86f6ef7091dc8ba714d96e4 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 9 Aug 2017 11:32:15 -0700 Subject: [PATCH] dm mpath: retry BLK_STS_RESOURCE errors Retry requests instead of failing them if an out-of-memory error occurs or the block driver below dm-mpath is busy. This restores the v4.12 behavior of noretry_error(), namely that -ENOMEM results in a retry.
