Subject: [PATCH] dm: Integrity errors should not cause failover
Date: Wed, 18 May 2011 00:49:49 -0400	[thread overview]
Message-ID: <yq18vu4fw9e.fsf@sermon.lab.mkp.net> (raw)


Integrity errors need to be passed to the owner of the integrity
metadata for processing. Consequently EILSEQ should be passed up the
stack.
