Perhaps we can use s_mtime and/or s_wtime in some way, I'm not sure
what is a parallel for that in xfs.
s_mtime - time-of-last mount
s_wtime - time-of-last mount, umount, freez, unfreez, remount, ...
Of course you'll need a per FS vector to access that.
But this will need some math foo to get the bits compacted correctly
just a thought.
