Subject: [PATCH] nvme: fix identify error status silent ignore
Date: Wed, 24 Jun 2020 16:56:59 -0700 [thread overview]
Message-ID: <20200624235659.28722-1-sagi@grimberg.me> (raw)
Patch 59c7c3caaaf8 intended to only silently ignore
non retry-able errors (DNR bit set) such that we can still
identify misbehaving controllers, and in the other hand
propagate retry-able errors (DNR bit cleared) so we don't
wrongly abandon a namespace just because it happens to be
temporarily inaccessible.
The goal remains the same as the original commit where this
was introduced but unfortunately had the logic backwards.
Fixes: 59c7c3caaaf8 ("nvme: fix possible hang when ns
scanning fails during error recovery")
