SubjectRe: 3-order allocation failed
Hi Rik,

A simple test seems to show problems with page allocator.

a) take a 6G RAM machine

b) take a 70G harddisk

c) mke2fs on it

observe lots of "0-order allocation failures" while looking at
/proc/meminfo reveals that I still have 5.1G of free memory (presumably
some of it in NORMAL zone, not just all HIGH)... Isn't buddy allocator
clever enough to break up the multi-page chunks if we need single pages?
I don't know.

Regards,
Tigran
