Yep.  The other place that directly called its ->clear_inode() also had
been bogus, BTW - logfs had been playing rather sick games with special
inodes and ended up open-coding just about everything on new_inode/iput
paths for those.  They needed that stuff evicted after all normal inodes,
but before the second call of invalidate_inodes() would scream about
surviving busy inodes.  I.e. that should've been happening in ->put_super();
no need to deal with handcrafted inodes that would sit outside of inode
list...
