Subject: [PATCH v8 08/31] locking/spinlock: introduce `_raw_spin_lock_init`
Date: Tue, 2 Aug 2022 03:49:55 +0200 [thread overview]
Message-ID: <20220802015052.10452-9-ojeda@kernel.org> (raw)
In-Reply-To: <20220802015052.10452-1-ojeda@kernel.org>
From: Wedson Almeida Filho <wedsonaf@google.com>
A Rust helper (introduced in a later patch) needs to call
`raw_spin_lock_init` with a passed key, rather than define
one in place.
In order to do that, this changes the `raw_spin_lock_init` macro
to call a new `_raw_spin_lock_init` function which takes the key
as an extra parameter.
