CONFIG_SLUB_DEBUG_ON=y in arch/lkl/defconfig?

[pscollins]

Is there a reason for this default? It looks like it causes a hit to performance, and since lkl doesn't make any changes to slub, I can't imagine it would catch many useful bugs.

No reason, just debug leftovers. I will disable it.

Thanks.

FYI I disabled it with

diff --git a/arch/lkl/defconfig b/arch/lkl/defconfig
