OK. > What's your confidence level for a 5.15-rc1 merge? 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. > It isn't terribly > well reviewed? Yeah that could be better, the pool of people deeply familiar with SLUB is not large, unfortunately. I hope folks will still step up!
