Subject: [PATCH v2 10/12] checkpatch: Deprecate srcu_read_lock_lite() and srcu_read_unlock_lite()
Date: Mon, 31 Mar 2025 14:03:12 -0700 [thread overview]
Message-ID: <20250331210314.590622-10-paulmck@kernel.org> (raw)
In-Reply-To: <eea8d42f-6d2d-485b-9bb9-4eb77a0e1f95@paulmck-laptop>
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.
