Subject: [PATCH 10/14] checkpatch: Deprecate srcu_read_lock_lite() and srcu_read_unlock_lite()
Date: Fri, 18 Apr 2025 12:09:42 -0400 [thread overview]
Message-ID: <20250418161005.2425391-11-joelagnelf@nvidia.com> (raw)
In-Reply-To: <20250418161005.2425391-1-joelagnelf@nvidia.com>
From: "Paul E. McKenney" <paulmck@kernel.org>
Uses of srcu_read_lock_lite() and srcu_read_unlock_lite() are better
served by the new srcu_read_lock_fast() and srcu_read_unlock_fast() APIs.
As in srcu_read_lock_lite() and srcu_read_unlock_lite() would never have
happened had I thought a bit harder a few months ago. Therefore, mark
them deprecated.
