From 6ead1bbc381a674c20f227dbe6f3a8c6f67ce7a2 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 14 Jan 2013 22:33:50 +0200 Subject: Bluetooth: Add a new workqueue for hci_request operations The hci_request function is blocking and cannot be called through the usual per-HCI device workqueue (hdev->workqueue). While hci_request is in progress any other work from the queue, including sending HCI commands to the controller would be blocked and eventually cause the hci_request call to time out. This patch adds a second workqueue to be used by operations needing hci_request and thereby avoiding issues with blocking other workqueue users.
