Subject: [PATCH 4/7] checkpatch: Mark rcu_read_lock_tasks_trace() and friend BPF-only
Date: Thu, 7 May 2026 10:09:47 -0700 [thread overview]
Message-ID: <20260507170950.2040199-4-paulmck@kernel.org> (raw)
In-Reply-To: <eeeda48e-03ed-428a-847d-5a0b56508b68@paulmck-laptop>
The rcu_read_lock_tasks_trace() and rcu_read_unlock_tasks_trace()
functions are intended for use only by BPF. Therefore, add them to
the list of functions that checkpatch complains about outside of BPF
(and of course, RCU).
