kernel dm snapshot: Load metadata on table creation not resumption.
Last modified: 2007-11-30 17:07:21 EST
Move snapshot metadata loading to happen when table is created instead
of when device is resumed. Origin writes don't trigger exceptions until
snapshot table becomes active (when resume() is called on snapshot).
