Subject: [PATCH] dm mpath: retry BLK_STS_RESOURCE errors
Git-commit: 68515cc72191f5c5d86f6ef7091dc8ba714d96e4
Patch-mainline: v4.13
References: fate#322738,fate#322919,fate#322950,fate#323773
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.
Fixes: 2a842acab109 ("block: introduce new block status code type")
