device-mapper-multipath-0.7.1-1.gitf21166a

- Update Source to the latest upstream commit
- Add 0001-libmultipath-add-comment-about-resuming.patch
  * posted upstream
- Add 0002-multipath-attempt-at-common-multipath.rules.patch
  * under discussion upstream
- Add 0003-RH-fixup-udev-rules-for-redhat.patch
  * Redhat uses different udev rules that some other distros, so multipath
    has run at a different time. Not all upstream distros link /sbin and
    /usr/sbin either.
- Add 0004-RH-Remove-the-property-blacklist-exception-builtin.patch
  * Allow multipath to be used on devices without multiple paths. NAK'ed
    upstream, but requested by Red Hat
- Add 0005-RH-don-t-start-without-a-config-file.patch
  * Don't start multipath unless a config file exists. NAK'ed upstream,
    but requested by Red Hat
- Add 0006-RH-use-rpm-optflags-if-present.patch
  * Make the build system fedora friendly
- Add 0007-RH-add-mpathconf.patch
  * Add tool to help configure multipath with Red Hat defaults.
- Add 0008-RH-add-wwids-from-kernel-cmdline-mpath.wwids-with-A.patch
  * Make multipath able to claim devices based on the kernel command line
    NAK'ed upstream but requested by Red Hat
- Add 0009-RH-trigger-change-uevent-on-new-device-creation.patch
  * under discussion upstream

+Subject: [PATCH] RH: trigger change uevent on new device creation
+
+When multipath first sees a path device with user_friendly names
+enabled, it can't know if the device should be multipathed. This means
+that it will not claim the device in udev.  If the device is eventually
+multipathed, multipath should trigger a change uevent to update the udev
+database to claim the device.
+
+This also reverts commit 64e27ec066a001012f44550f095c93443e91d845.
