Subject: [PATCH net-next v3 0/2] Add an assert in napi_consume_skb()
Date: Tue, 24 Nov 2020 18:49:27 +0800	[thread overview]
Message-ID: <1606214969-97849-1-git-send-email-linyunsheng@huawei.com> (raw)

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:
V3: add comment to emphasize the ambiguous semantics
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()
