hselasky 4a8d8f7fba To support userspace audio daemons like Virtual OSS, /dev/sndstat is ... made writeable by the root user. Userspace audio daemons can add or update an entry in /dev/sndstat by doing a single system write call to any /dev/sndstat file descriptor handle. When the audio daemon closes the file handle or is killed the entry disappears. While at it, cleanup the sound status code a bit: - keep the device list sorted to avoid sorting the list every time a /dev/sndstat read request is made. - factor out locking into a pair of locking macros. - use the sound status lock to protect all per file handle states, when generating the output for /dev/sndstat and when removing or adding sound status devices. This way sndstat_acquire() and sndstat_release() become superfluous and can be removed. Reviewed by: mav @ Differential Revision: https://reviews.freebsd.org/D5191		2016-02-09 17:09:14 +00:00
