1.26.4. RHBA-2011:0864: device-mapper-multipath bug fix update

Updated device-mapper-multipath packages that fix one bug are now available for Red Hat Enterprise Linux 5.
The device-mapper-multipath packages provide tools to manage multipath devices by giving the "dm-multipath" kernel module instructions on what to do, as well as by managing the creation and removal of partitions for Device-Mapper devices.
This update fixes the following bug:
* After acquiring their resource locks, multipathd's threads did not check if they were canceled before accessing their resources. This caused multipathd to close with a segmentation fault on shutdown, if a thread attempted to access a resource after it was canceled. Now all multipathd threads check if they are canceled before accessing their resources. (BZ#704470)
All users of device-mapper-multipath are advised to upgrade to these updated packages, which fix this bug.
