[dm-devel] [PATCH] 2.4: dm-snapshot.c: Call unlockfs() on error from register_snapshot()



[Sent this earlier, but it looks like it's gotten lost, so re-sending. Sorry 
if this is a duplicate.]

In snapshot_ctr(), if the call to register_snapshot() fails, we need to
unlock the origin's filesystem (if the VFS-lock patch has been applied).
