[Lse-tech] 2.6.0-test9-mjb1

[Martin J. B. <mb...@ar...>]

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.
