SubjectRe: Purpose of the mm/slab.c changes

Besides this, i don't get how a LIFO could help you.

Actually, there is a school of thought which says that if you make the
time between the free and re-alloc of a piece of memory as long as
possible you increase the likelyhood that any dirty cache lines of
that memory can be sent back to memory "quietly" during natural L2
cache line replacement.

I don't necessarily subscribe to these ideas, but I do see the
potential benefits. For one thing, it does have the potential to lead
to more repeatable timings, at least in theory.
