Subject: [PATCH 15/20] filelock: clean up locks_delete_block internals
Date: Tue, 16 Jan 2024 14:46:11 -0500	[thread overview]
Message-ID: <20240116-flsplit-v1-15-c9d0f4370a5d@kernel.org> (raw)
In-Reply-To: <20240116-flsplit-v1-0-c9d0f4370a5d@kernel.org>

Rework the internals of locks_delete_block to use struct file_lock_core
(mostly just for clarity's sake). The prototype is not changed.
