Log message:
	Unlike 'mirror' segtype, 'raid1' should perform flush	on suspend.
	
	The 'mirror' segtype and 'raid1' segtype both set the 'MIRRORED' flag.
	However, due to differences in the way these device-mapper targets behave
	'mirror' must be suspended with the 'noflush' option and 'raid1' does not
	have to be.
	
	This patch ensures that when the 'MIRRORED' flag is checked to see if
	'noflush' is needed that it does not also set it for 'raid1' by mistake.

Log message:
	Fix the way RAID meta LVs are added to the dependency tree.
	
	Similar to the "mirror" segment type's log device, _add_dev_to_dtree should
	be called and not _add_lv_to_dtree when adding metadata sub-LVs to the deptree.
	Since _add_lv_to_dtree was being called, 'origin_only' could be set if a
	snapshot sits on top of the RAID device.  This would cause the actual device
	that needed to be added to be skipped in favor of the non-existant device,
	"<foo>-real".

Log message:
	Never scan a device which is using the error target
	
	A merged snapshot's DM device is made to use the "error" target as part
	of lvm's transaction to merge a snapshot.  This snapshot merge use-case
	aside, any device using the error target shouldn't be scanned.

Log message:
	This patch fixes a potential for I/O to hang and LVM commands
	to block when a mirror under a snapshot suffers a failure.
	
	The problem has to do with label scanning.  When a mirror suffers
	a failure, the kernel blocks I/O to prevent corruption.  When
	LVM attempts to repair the mirror, it scans the devices on the
	system for LVM labels.  While mirrors are skipped during this
	scanning process, snapshot-origins are not.  When the origin is
	scanned, it kicks up I/O to the mirror (which is blocked)
	underneath - causing the label scan (an thus the repair operation)
	to hang.
	
	This patch simply bypasses snapshot-origin devices when doing
	labels scans (while ignore_suspended_devices() is set).  This
	fixes the issue.

	When activating a merging origin it is valid, and expected, to not have

Log message:
	Eliminate extra ioctls just to check open_count in _add_new_lv_to_dtree.
	
	DM >= 4.7.0 always returns open_count so just use the associated nodes'
	existing info.
	
	Introduce _cached_info() to get an LV's cached info.
