David Anderson 29e6bf282f Add dm-snapshot targets to libdm and dmctl. ... This adds DmTargetSnapshotOrigin and DmTargetSnapshot. The latter target can handle both "snapshot" and "snapshot-merge" targets. The syntax for dmctl is as follows: dmctl create <name> snapshot <start> <num_sectors> <base_device> \ <cow_device> <P|N> <chunk_size> dmctl create <name> snapshot-merge <start> <num_sectors> <base_device> \ <cow_device> <chunk_size> dmctl create <name> snapshot-origin <start> <num_sectors> <device> Bug: N/A Test: libdm_test gtests Change-Id: I8eef987cb92121e81bedd37b9a66fad04c7a23a3		2019-05-06 13:59:44 -07:00
