[dm-devel] [PING / RESEND] handling reservation conflicts in dm-mpath

[Christoph Hellwig]

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?
