--- Comment #2 from Eric Sandeen <[email protected]> --- Freeing it when the module is unloaded should be sufficient.In normal use, unmounting a filesystem creates a hole in the table, which the next mount can fill.
If you mount a lot of unique UUID filesystems without unmounting any in between, the table will grow accordingly, and unmounting won't shrink it - i.e. the table only grows as the number of concurrently mounted filesystem grows, but that doesn't seem like a particularly critical problem to fix.
If anyonereally cares about this he or she should just kill the uuid table entirely. We can simple walk a list of mounted xfs filesystems and check their uuids. The VFS even keeps a list already, which we probably could use if we are careful.
Bonus points for implementing this in a way so that other filesystems could share the code.
