For accessing the snd_timer_user queue indices, we take tu->qlock. But it's forgotten in a couple of places. The one in snd_timer_user_params() should be safe without the spinlock as the timer is already stopped. But it's better for consistency. The one in poll is just a read-out, so it's not inevitably needed, but it'd be good to make the result consistent, too.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
