Linus Torvalds 4a621e2910 A couple of fixes for tracing: 
- Prevent a NULL pointer dereference in the error path of RTLA tool
 
 - Fix an infinite loop bug when reading from the ring buffer when closed.
   If there's a thread trying to read the ring buffer and it gets closed
   by another thread, the one reading will go into an infinite loop
   when the buffer is empty instead of exiting back to user space.
