[RFC] mballoc patches

["Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>]

Alex actually pointed me the new mballoc patches at
ftp://ftp.clusterfs.com/pub/people/alex/mballoc3

The series is the forward port of the same on top of
d4ac2477fad0f2680e84ec12e387ce67682c5c13 (v2.6.23-rc2)


I guess the mballoc3 patch at clusterfs.com is based on
a patched ext3(I guess it is ext3 + extent tree local to
clusterfs ? ). The following series is based on ext4.


I tested the changes with different blocks per group
combination and it seems to be working fine. (The last
series did panic with mke2fs -g 800 )


I will now look at splitting this to smaller patches.

NOTE : I am not sure whether patch 2 will be able to make the list.
if not is there a place i can ftp/scp them so that others can access
the same ?

I haven't split the patches in any order and didn't bothered to
write any meaningful commit messages since this is mostly work in
progress.
