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.
