One small warning though. Please don't apply that patch
yet because I fixed 3 more small problems today. I'll
send you an updated patch...

- the compile warnings are fixed
- in try_to_free_pages(), we forgot to set
PF_MEMALLOC in current->flags (oops)
- in grow_buffers(), in case we cannot get a
buffer head, we must unlock the page

A patch against 2.4.0-test9-pre8 with these 3 changes will
be on its way once I've tested it a bit...

regards,

Rik
