Subject: [PATCH 04/17] hlist_bl: Prepare for split_locks
Date: Fri,  9 Apr 2021 03:51:18 +0100	[thread overview]
Message-ID: <20210409025131.4114078-5-willy@infradead.org> (raw)
In-Reply-To: <20210409025131.4114078-1-willy@infradead.org>

Make hlist_bl_lock() and hlist_bl_unlock() variadic to help with the
transition.  Also add hlist_bl_lock_nested().
