All of the patches which move from using iget() to iget_unlocked()
should in theory (if they are well written) be standalone and not have
any prerequisites, and a good thing to apply in and of themselves.  

So maybe the right thing to do is to push all of them right away, and
then if they all can go in safely w/o breaking filesystems, we can
actually do the deed about removing the iget() interface itself, and
if not, it can wait until 2.6.26.  It's not really that big of a deal
to actually nuke the interface itself, as long as we are gradually
reducing our usage of it....  Or is there some patch which David is
trying to push that desperately depends on iget() going away?
