8 to implement many of the standard POSIX I/O system calls, including read(),

80 buf_setup() is called early in the I/O process, when streaming is being
81 initiated; its purpose is to tell videobuf about the I/O stream.  The count
101 When a buffer is queued for I/O, it is passed to buf_queue(), which should
110 used.  The driver should ensure that there is no I/O active on the buffer,
125 One way to ensure that a buffer is no longer under I/O is to pass it to:

239 - those associated with streaming I/O - turn almost directly into videobuf
