device-mapper-multipath/0075-RHBZ-1056976-reload-flag.patch
Benjamin Marzinski d9ed5f9739 device-mapper-multipath-0.4.9-63 
Add 0074-RHBZ-1056976-dm-mpath-rules.patch
  * Add rules to keep from doing work in udev if there are no
    active paths, or if the event was for a multipath device
    reloading its table due to a path change.
Add 0075-RHBZ-1056976-reload-flag.patch
  * multipath code to identify reloads that the new rules can
    ignore
Add 0076-RHBZ-1056686-add-hw_str_match.patch
  * add a new default config paramter, "hw_str_match", to make user
    device configs only overwrite builtin device configs if the
    identifier strings match exactly, like the default in RHEL6.
