List delete cannot fail, so there is no reason to test for error.

02f6f4902f Disable partial activation for thin LVs and LVs with all missing segments
Count number of error and existing areas and if there is no existing area
for the LV avoid its activation.

Always disable partial activatio for thin volumes.

For mirrors currently put in hack to let it pass with a special name
since current mirror code needs to activate such LV during some operations.

cb09dc1274 Use suspend|resume_origin_only when up-converting RAID LVs, as mirrors do.
Failure to do so results in "Performing unsafe table load while X device(s) are
known to be suspended" errors.  While fixing the problem in this way works and
is consistent with the way the mirror segment type does it, it would be nice
to find a solution that uses the generic suspend/resume calls.

Also included in this check-in are additions to the test suite that perform
conversions on RAID LVs under a snapshot.  These tests are disabled for the
time being due to a kernel bug that is yet to be tracked down.

fe5199c506 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".

do not exist - since for private devices we are not creating them.

a563ef56b8 Drop hack in segtype reporting
Since striped name function knows when to report 'linear' instead of
'stripe' type name - drop it from this place.

This fixes problem when reporting segtype e.g. for thin-pool which
is also using area_count=1 to store thin data device reference.

It also returns properly strduped memory instead of badly casted const char*.

6bcd3263c2 Preserve exclusive activation of cluster mirror when converting.
This patch to the suspend code - like the similar change for resume -
queries the lock mode of a cluster volume and records whether it is active
exclusively.  This is necessary for suspend due to the possibility of
preloading targets.  Failure to check to exclusivity causes the cluster target
of an exclusively activated mirror to be used when converting - rather than
the single machine target.
