From: Marcel Holtmann Date: Wed, 4 Sep 2013 01:08:38 +0000 (-0700) Subject: Bluetooth: Only schedule raw queue when user channel is active X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=52de599e04e8767b0d9b7874451cb5db91a4a70b;p=deliverable%2Flinux.git Bluetooth: Only schedule raw queue when user channel is active When the user channel is set and an user application has full control over the device, do not bother trying to schedule any queues except the raw queue. This is an optimization since with user channel, only the raw queue is in use.
