[Bug 956128] [NEW] find_multipaths feature missing from upstream

[Peter Petrakis]

Public bug reported:

There's an interesting feature called find_multipaths that was first
mentioned here on dm-devel in July 2011.

https://www.redhat.com/archives/dm-devel/2011-July/msg00102.html

It's now the corner stone of dm multipath configuration in the RHEL 6 DM Multipath configuration guide
https://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/DM_Multipath/config_file_blacklist.html

What it basically allows is autoprobing of devices to safely enable multpath on luns that satisfy
the proper criteria. It has the power to reduce a multipath.conf configuration to a single line.

Alas it doesn't exist in the upstream sources, only as a patch in RH's multipath package
  0021-RHBZ-558636-add-find-multipaths.patch

This bug exists to track the status of this feature and it's ultimate integration into upstream
or into our multipath-tools package.

** Affects: multipath-tools (Ubuntu)
     Importance: Undecided
         Status: New
