Hi,

In 169ebd90131b2ffca74bb2dbe7eeacd39fb83714 commit, writeback doesn't
__iget()/iput() anymore.

This means nobody moves the inode to lru list. I.e.

	new_inode()
	dirty_inode()
	iput_final()
		/* keep inode without adding lru */
	flush indoes
        /* clean inode is not on lru */

I noticed this situation in my FS though, I think the same bug is on all
FSes of linus tree too, after this commit.

Am I missing the something?

Thanks.
