Subject: [PATCH] dm mpath: add DM device name to Failing/Reinstating path log
Git-commit: 04867370ec40b708bd335df641182ddab0c59685
Patch-mainline: v5.8-rc1
References: bsc#1175995,jsc#SLE-15608
messages
When there are many DM multipath devices it really helps to have
additional context for which DM device a failed or reinstated path is
part of.
