Merge branch 'net-lockless-skb_attempt_defer_free'
Eric Dumazet says:
====================
net: lockless skb_attempt_defer_free()
Platforms with many cpus and relatively slow inter connect show
a significant spinlock contention in skb_attempt_defer_free().
This series refactors this infrastructure to be NUMA aware,
and lockless.
Tested on various platforms, including AMD Zen 2/3/4
and Intel Granite Rapids, showing significant cost reductions
under network stress (more than 20 Mpps).
