Subject: [PATCH 6/8] net: Add missing annotation for *netlink_seq_start()
Date: Wed, 11 Mar 2020 01:09:06 +0000 [thread overview]
Message-ID: <20200311010908.42366-7-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200311010908.42366-1-jbi.octave@gmail.com>
Sparse reports a warning at netlink_seq_start()
warning: context imbalance in netlink_seq_start() - wrong count at exit
The root cause is the missing annotation at netlink_seq_start()
Add the missing __acquires(RCU) annotation
