Subject: [PATCH net-next v2 0/2] Add an assert in napi_consume_skb()

This patch introduces a lockdep_assert_in_softirq() interface and
uses it to assert the case when napi_consume_skb() is not called in
the softirq context.

Changelog:
V2: Use lockdep instead of one-off Kconfig knob

Yunsheng Lin (2):
  lockdep: Introduce in_softirq lockdep assert
  net: Use lockdep_assert_in_softirq() in napi_consume_skb()
