What do you mean with global? Global is one thing, but taking highmem
into account for calculating the limit is another thing. The
nr_free_buffer_pages exists exactly to avoid taking highmem into account
for the dirty memory limits. 2.6 must also ignore highmem in the dirty
memory limits like 2.4 does. I'd be surprised if somebody broke this in
2.6. As far as I can tell, while writing to a blkdev it cannot make any
difference if you've 4G or 1G of ram because of that (I mean on x86 of
course).
