Steven Rostedt (Google) 4ecaf7e98a tracing: Have memmapped ring buffer use ioctl of "R" range 0x20-2F ... To prevent conflicts with other ioctl numbers to allow strace to have an idea of what is happening, add the range of ioctls for the trace buffer mapping from _IO("T", 0x1) to the range of "R" 0x20 - 0x2F.
