Subject: [RFC 08/22] Bluetooth: Remove sk_backlog usage from L2CAP
Date: Sat, 17 Dec 2011 19:29:28 -0200	[thread overview]
Message-ID: <1324157382-1815-9-git-send-email-padovan@profusion.mobi> (raw)
In-Reply-To: <1324157382-1815-8-git-send-email-padovan@profusion.mobi>

From: "Gustavo F. Padovan" <padovan@profusion.mobi>

We run everything in the same lock now. The backlog queue is useless now
