Subject: [PATCH 1/2] cxgb4: Add missing annotation for service_ofldq()
Date: Wed, 29 Apr 2020 23:57:22 +0100 [thread overview]
Message-ID: <20200429225723.31258-2-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200429225723.31258-1-jbi.octave@gmail.com>
Sparse reports a warning at service_ofldq()
warning: context imbalance in service_ofldq() - unexpected unlock
The root cause is the missing annotation at service_ofldq()
Add the missing __must_hold(&q->sendq.lock) annotation
