Absolutely.

We even used to have something like this on a per-cpu basis but using
generic SLAB is so much better for caching and NUMA that we got rid of
that.

Every sk_buff private "quicklist" pool implementation you
see should essentially be NAK'd from the get go, it's
meaningless and if it's really needed one should investigate
why SKB allocations become such a problem instead of papering
over the issue. :-)
