Subject: [PATCH 05/11] sched/fair: Add missing annotation for nohz_newidle_balance()
Date: Sun,  9 Feb 2020 22:37:39 +0000	[thread overview]
Message-ID: <ca8c5c88a5882a4b7e243be73b4f0402e9da9cc2.1581282103.git.jbi.octave@gmail.com> (raw)
In-Reply-To: <cover.1581282103.git.jbi.octave@gmail.com>

Sparse reports a warning at nohz_newidle_balance()
warning: context imbalance in nohz_newidle_balance() - wrong count at exit
The root cause is a missing annotation

Add the missing __must_hold(this_rq->lock)
