Hello, Is it ever possible for a superblock for a mounted filesystem to be free'd without a previous call to unmount the filesystem? I need to be certain that the function cleancache_invalidate_fs, which is at the moment called by deactivate_locked_super (fs/super.c) [1], is called before every free on a superblock of cleancache-enabled filesystems. Is this already the case or are there situations in which this does not happen? It would be interesting to know this, as we are planning to have cleancache save pointers to superblocks of every mounted cleancache-enabled filesystem [2] and it would be fatal if a superblock is free'd without cleancache being notified.
