Hello,

Thanks for the great work. Just to comment that switching to SLUB seems to
partially address Bug#861964:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=861964

Perhaps a comment on that bug is in order, if not closing it outright?

Regards,

Yes, let's change to SLUB.  I think SLUB_DEBUG and
SLAB_FREELIST_HARDENED should be enabled, except on armel/marvell.
