This one is a little nasty in that it seems to remove the possibility of
a failure at this point, and with xfs in there we do a write_buffer_locked
call in place of the submit_bh we can definitely fail. I am guessing
a little bit since I need more context to really work it out, and I
am not really feeling like patching up yet another kernel version here.

I think you should just apply the rmap patch to a vanilla kernel and
take the resulting vmscan.c, then on the line which does this:
if (PageDirty(page) && page->mapping) {
right at the end of the patch, change it to:
if ((PageDirty(page) || DelallocPage(page)) && page->mapping) {
but I would really have to see the whole file to say for sure.
