Subject: [RFC 16/22] Bluetooth: convert info timer to delayed_work
Date: Sat, 17 Dec 2011 19:29:36 -0200 [thread overview]
Message-ID: <1324157382-1815-17-git-send-email-padovan@profusion.mobi> (raw)
In-Reply-To: <1324157382-1815-16-git-send-email-padovan@profusion.mobi>
From: "Gustavo F. Padovan" <padovan@profusion.mobi>
Another step of remove interrupt context from Bluetooth Core.
Use the system workqueue.
