This is a new ext4 patchset which is synchronized with the 2.6.25-rc1

release.  No new patches were added, just patches removed because they

have been accepted upstream.
At this point, I do not anticipate any more patches to ext4 that will

change the on-disk format.  The focus is on the optimization patches

(i.e., delayed allocation support) fine-tuning performance, and fixing

any bugs which turn up as more people use ext4.
