[dm-devel] [PATCH 6/7] dm-mpath: Retry BLK_STS_RESOURCE errors

[Bart Van Assche]

Retry requests instead of failing these 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: commit 2a842acab109 ("block: introduce new block status code type")
