1544/* Original comment: FIXME: ROTATE_BUFS is a hack to cycle through
1545 * bufs until freelist code is used. Note this hides a problem with
1546 * the scratch register * (used to keep track of last buffer
1547 * completed) being written to before * the last buffer has actually
1548 * completed rendering.
1549 *
1550 * KW: It's also a good way to find free buffers quickly.
1551 *
1552 * KW: Ideally this loop wouldn't exist, and freelist_get wouldn't
1553 * sleep. However, bugs in older versions of radeon_accel.c mean that
1554 * we essentially have to do this, else old clients will break.
1555 *
1556 * However, it does leave open a potential deadlock where all the
1557 * buffers are held by other clients, which can't release them because
1558 * they can't get the lock.
