Eh, wait. Those are operations on namespace, but at some moment you need
to clean the bit in inode bitmap. You can't do it before the last close()
and it definitely alters the filesystem. fsck will pick them up, but that
may be *not* a desired result. Dirty filesystem is definitely not desired
anyway.
