. A number of fixes against the ext3 work which Alex and I have been doing.
This code is stable now. I'm using it on my main SMP desktop machine.

These are major changes to a major filesystem. I would ask that
interested parties now subject these patches to stresstesting and to
performance testing. The performance gains on SMP will be significant.

. I dropped the kexec patches. Mainly because the sheer extent of the -mm
diffs is getting in the way of other work, and the kexec patches
significantly altered the arch/i386 code where other things are happening.

Changes since 2.5.69-mm9:

linus.patch
