Subject: [PATCH 12/38] mwifiex: Convert ack_status_frames to XArray
Date: Tue, 20 Aug 2019 15:32:33 -0700 [thread overview]
Message-ID: <20190820223259.22348-13-willy@infradead.org> (raw)
In-Reply-To: <20190820223259.22348-1-willy@infradead.org>
From: "Matthew Wilcox (Oracle)" <willy@infradead.org>
Straightforward locking conversion; the only two points of note is that we
can't pass the address of the tx_token_id to xa_alloc() because it's too
small (an unsigned char), and mwifiex_free_ack_frame() becomes inlined
into its caller.
Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
