	Same scenario on link(2) ends up with
* ST_LINKFILE created, inserted into the link chain and left around,
without being present in any hash chain
* target becoming positive hashed dentry, as if link(2) has succeeded,
so dcache lookups will be finding it (for a while)
* unlink(2) on source will have very interesting effects, what with
the attempts to move ST_FILE entry into the directory presumed to
contain ST_LINKFILE one, removing ST_LINKFILE from it at the same time.
