Shouldn't the put_cpu() be after ac-ac_lg is no longer being used?
I guess there would otherwise be a danger of other processes using
the same s_locality_groups[] struct?

Hmm, but part of the issue would be how to request the extra data, and
what offset
be caused by the fact the patches were changed
at one point from delalloc-atop-mballoc to mballoc-atop-delalloc, and
something was missed in that conversion.
Have you tried O_DIRECT? That is another way to access mballoc w/o
using delalloc.

ext3 for most of these features
against older vendor kernels (SLES10 2.6.16, RHEL5 2.6.18) if that is
of interest to you (only delalloc isn't included in the existing Lustre
patch set, but I believe Alex had delalloc patches for 2.6.18 kernels
in the past).

Also, some users might want the ability to use features of ext4 w/o

might also consider running sparse on it ext3/ext4 in case you missed an
le32_to_cpu() or something.

(c) The actual speedup depends on how full the filesystem is, but since ext*
usually has way too many inodes, it is generally pretty good.
