| |
The patchset contains mainly scalability and NUMA stuff, and anything else that stops things from irritating me. It's meant to be pretty stable, not so much a testing ground for new stuff.
I'd be very interested in feedback from anyone willing to test on any platform, however large or small.
NOTE - you will have to apply -bk3 before applying this release. ftp://ftp.kernel.org/pub/linux/kernel/v2.5/snapshots/patch-2.5.64-bk3.bz2 ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/2.5.64/patch-2.5.64-bk3-mjb3.bz2
