As far as I can tell from reading the code, the time_after()

right. that's why I didn't want to move used lockres to tail :)<br>

No. There is no need for time ordering. Or, am I missing something?<br>
<br>
We delay the purge incase the file system changes its mind and wants<br>
to reuse it. By delaying, we hold onto the mastery information. That's
it.<br>

So, should we preserve this? or purge the lockres when it's on purge
list? OR we could just update the last_used and move it to end of the
list if it can be purged.<br>
