Currently the XFS freezer doesn't solve a deadlock automatically

and we rely on administrators for ensuring that the freezer will not

access the filesystem.

And even if the wrong freezer causes a deadlock, it can be solved

by other unfreeze process(unfreeze command).


So I don't think the freezer itself needs to solve the deadlock.

I think the timeout is effective for a unexpected deadlock

and the timeout extending feature is very useful

as Dmitri proposed.


Cheers, Takashi
