[linux-lvm] How to check if thin volume or snapshot was ever activated

[Gionatan Danti]

Dear all,
as you know, a thin snapshot does have the "k" (skip activation) flag 
set, so one has to force activation by ignoring the flag (or removing 
the flag itself).

I wonder: can we detect if a volume/snapshot was *ever* activated? My 
reasoning is that a never-activated snapshot surely did not receive any 
application writes, so it can be safely removed (ignoring snapshot 
retention policy).

Regards.
