Subject: [PATCH] dm: Integrity errors should not cause failover
Date: Tue, 08 Mar 2011 01:54:00 -0500	[thread overview]
Message-ID: <yq1aah6drw7.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.
