Subject: [PING / RESEND] handling reservation conflicts in dm-mpath
Date: Tue,  2 Aug 2016 14:36:31 +0200	[thread overview]
Message-ID: <1470141392-25479-1-git-send-email-hch@lst.de> (raw)

Hannes sent this patch a bit more than a year ago, but it got silently
dropped.  When using the pNFS SCSI layout we can easily hit a
failover "livelock" without it as the reservation conflicts on a
newly detected device that doesn't have layouts yet, or after a fency
will keep failing over from one path to another for no reason at all.

Any chance to get it into mainline now?
