Subject: [PATCH rcu 3/5] scftorture: Account for weight_resched when checking for all zeroes
Date: Wed, 15 Sep 2021 16:41:39 -0700	[thread overview]
Message-ID: <20210915234141.3907301-3-paulmck@kernel.org> (raw)
In-Reply-To: <20210915234117.GA3907188@paulmck-ThinkPad-P17-Gen-1>

The "all zero weights makes no sense" error is emitted even when
scftorture.weight_resched is non-zero because it was left out of
the enclosing "if" condition.  This commit adds it in.

Fixes: 1ac78b49d61d4 ("scftorture: Add an alternative IPI vector")
Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
