Subject: [PATCH 6/7] rcu: Simplify param_set_next_fqs_jiffies() by applying clamp_val()
Date: Thu, 7 May 2026 10:09:49 -0700 [thread overview]
Message-ID: <20260507170950.2040199-6-paulmck@kernel.org> (raw)
In-Reply-To: <eeeda48e-03ed-428a-847d-5a0b56508b68@paulmck-laptop>
This commit replaces a nested ?: sequence with clamp_val(). This does
not reduce the number of lines of code, but it does simplify the line
that it modifies.
