[Devel] [PATCH rh7 0/2] ploop: implement push_backup auto destroy

[Maxim Patlasov]

If backup tool dies or is killed, we cannot continue push_backup anyway
(because next instance of backup tool runtime won't know which blocks to
push_backup). So, it's useless to keep in-kernel push_backup state after
userspace part disappeared.

The patch set implements auto-destroy: ploop detects when userspace goes
away, then aborts and releases in-kernel push_backup.
