[PATCH net-next 0/5] net: give napi_threaded_poll() some love

[Eric Dumazet <edumazet@google.com>]

There is interest to revert commit 4cd13c21b207
("softirq: Let ksoftirqd do its job") and use instead the
napi_threaded_poll() mode.

https://lore.kernel.org/netdev/140f61e2e1fcb8cf53619709046e312e343b53ca.camel@redhat.com/T/#m8a8f5b09844adba157ad0d22fc1233d97013de50

Before doing so, make sure napi_threaded_poll() benefits
from recent core stack improvements, to further reduce
softirq triggers.

Eric Dumazet (5):
  net: add debugging checks in skb_attempt_defer_free()
  net: do not provide hard irq safety for sd->defer_lock
  net: move skb_defer_free_flush() up
  net: make napi_threaded_poll() aware of sd->defer_list
  net: optimize napi_threaded_poll() vs RPS/RFS
