When close a file it will be deferred to call the fput(), which
will hold the inode's i_count. And when unmounting the mountpoint
the evict_inodes() may skip evicting some inodes.
If encrypt is enabled the kernel generate a warning when removing
the encrypt keys when the skipped inodes still hold the keyring:
This does not make sense. Unmounting is only possible once all the files on the
filesystem have been closed.
Yeah, but I didn't see any where is checking this. Maybe I missed
something important.
