Subject: [PATCH] sched: Remove nr_spread_over for sched debug
Date:   Sat,  4 Nov 2023 17:12:30 +0800
Message-Id: <20231104091230.128516-1-s921975628@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

As the statistic for nr_spread_over isn't tracked in scheduler
anymore after the EEVDF changes, we should just remove it.
