The code in question originally came from ext2, when the a_ops used in
XIP mode did not have a readpage function.  And since there is an
outstanding XIP patch set that Matthew Wilcox has been working on, I
was going to NACK this.  Howeveer, it looks like the lines in question
are getting removed in the most recent version of the XIP patch set
that I've seen, so it it seems the only problem is this will cause a
minor patch conflict with XIP.

So I'll accept this, and assume the XIP folks aren't going to object....
