ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.70/2.5.70-mm1/ . 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.
