| |
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.

Since 2.5.65-mjb1 (~ = changed, + = added, - = dropped)
Notes: Broke shpte out separately, it seems a little fragile under certain workloads at the moment.
Now in Linus' tree:
