[dm-devel] [PATCH <missing> of 8: MD new mddev flag value



Sorry, I missed a patch that should have gone in-between the MD and DM
patches:

	md-backout-dm-dirty-log.patch
	md-minor-updates.patch
	md-fix-null-pointer-deref.patch

->	md-new-mddev-flag-value.patch

	dm-raid-seed-module.patch
	dm-target-callbacks-and-congestion-fn.patch
	dm-unplug-callback.patch
	dm-raid-iterate_devices-and-io_hints.patch
	dm-raid-suspend-and-resume-fns.patch

Mea Culpa,
 brassow

Add a new possible flag for the mddev structure.

The flag is used by device-mapper to tell MD to override the
information it finds in the superblock/bitmap WRT the
overall [re]sync of the array.
