Re: [dm-devel] latest multipath-tools from git breaks EMC CX



Most certainly the 8af5a2b1b5e4d3a457f5bb477214356385087eae commit is
the culprit : I did a bit of spliting in path discovery, and introduced
a new fn to get the sysfs bus that I use as a switch to choose a
discovery template.

Reading your output, I would say the bus fetching went wrong.

Well, revert it or debug it :/

Strange it didn't blew on me ...
