Doc Text:
Cause: multipath was treating files in /etc/multipath/conf.d that didn't end with .conf as config files Consequence: Multipath could try to parse non-config files, or backups of config files. Fix: multipath now only parses files ending in .conf from /etc/multipath/conf.d Result: multipath now only parses config files
