Subject: [PATCH net-next RESEND 0/2] fix rculist sparse errors
Date: Wed, 10 Dec 2014 16:46:05 +0800	[thread overview]
Message-ID: <1418201167-9591-1-git-send-email-ying.xue@windriver.com> (raw)

When hlist_for_each_entry_continue_rcu_bh() gets "next" pointer of
hlist_node structure through rcu_dereference_bh(), sparse warning
appears as the "next" pointer is not annotated as __rcu. So if
the "next" pointer is accessed with hlist_next_rcu() macro, the
__rcu annotation will be added to the pointer. As a consequence,
sparse warning is eliminated too.

The similar errors also appear in hlist_for_each_entry_continue_rcu()
and hlist_for_each_entry_from_rcu().

In this version, CC more people like Paul E. McKenney and lkml mail
list.
