device-mapper-multipath enhancement update

An enhanced device-mapper-multipath package is now available.

The device-mapper-multipath package provides tools to manage multipath
devices by instructing the device-mapper multipath kernel module what to do.

Bugs fixed in this update include:

-device-mapper-multipath did not work correctly with GNBD devices

-multipath didn't correctly read /var/lib/multipath/bindings, so multiple
devices could be assigned the same user-friendly-name

-multipath -l an -ll occasionally showed incorrect information

-multipath devices were not being created correctly for luns with a minor
number of greater than 256

-multipath would fail on scsi devices with too large serial numbers.

-multipath devices were not being correctly configured for various IBM
storage devices.

Enhancements included in this update are:

-Improved autoconfiguration for HP and Hitachi storage devices

-device-mapper-multipath is now able to handle DASD devices

-ability to set and change the rr_min_io on a per-device basis
