Don Lewis ca219d048a Convert sndstat_lock from a mutex to an sx lock. sndstat_read() ... holds sndstat_lock across a call to uiomove(), which is not legal to do with a mutex because of the possibility that the data transfer could sleep because of a page fault. It is not possible to just unlock the mutex for the uiomove() call without introducing another locking mechanism to prevent the body of sndstat_read() from being re-entered. Converting sndstat_lock to an sx lock is the least complicated change. This is a candidate for RELENG_5. LOR: 030 MFC after: 4 days		2004-09-10 09:37:06 +00:00
