I'd say pretty good. It's part of RT patchset for a while (since early
July IIRC?) and there has been lot of testing there. Mike and Mel also
tested under !RT configs, and the bug report from Sven means the mmotm
in -next also gets testing. The fixups were all thanks to the testing
and recently shifted to smaller unusual-config-specific issues that
could be dealt with even during rcX stabilization in case there's more.

Yeah that could be better, the pool of people deeply familiar with SLUB
is not large, unfortunately. I hope folks will still step up!
