Subject: [PATCH 3/4] Docs/RCU/rculist_nulls: Fix hlist_head field name of 'obj'
Date: Thu, 18 May 2023 22:40:07 +0000 [thread overview]
Message-ID: <20230518224008.2468-4-sj@kernel.org> (raw)
In-Reply-To: <20230518224008.2468-1-sj@kernel.org>
The example code snippets on rculist_nulls.rst are assuming 'obj' to
have the 'hlist_head' field named 'obj_node', but a sentence is wrongly
mentioning 'obj->obj_node.next' as 'obj->obj_next'. Fix it.
