From 89ddeb8cb1383bfdfaaeb458f1c4a91e890cc60b Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Fri, 21 Dec 2012 20:23:34 +0000 Subject: dm persistent data: use DMERR_LIMIT for errors Nearly all of persistent-data is in the IO path so throttle error messages with DMERR_LIMIT to limit the amount logged when something has gone wrong.
