The final iput() calls ->clear_inode() (jffs2_clear_inode in case of jffs2)
and the inode has just been created, with no other in-core references
existing. Basically, that call was the only part of (required) iput() that
_was_ done there ;-)
FWIW, what's happening around ->clear_inode()/->delete_inode()/->drop_inode()
is a mess. This leak got found when I'd been looking through that crap;
results of sanitizing are in #evict_inode (vfs-2.6.git). I'm going to shift
that into for-next tomorrow, assuming it survives local beating. For now
I've just pulled jffs2-fixes in it...
