[PATCH tip/core/rcu 0/4] v2 Documentation and rcutorture changes for 3.9
Hello! The following are changes to documentation and rcutorture: 1. Export trace_clock_local() in order to allow rcutorture event tracing to emit the time of the beginning of the RCU read-side critical section at the point where a failure is detected. 2. Reduce rcutorture's read-side tracing to include only failures, thus cutting the number of events down to something reasonable (normally zero, in fact!). 3. Add atomic_xchg() to the list of atomic operations and memory barriers, courtesy of Richard Braun. 4. Make rcutorture's shuffler task also shuffle recently added rcutorture kthreads. Changes since v1: o Fixed build problem in #2 located by Randy Dunlap based on diagnosis from Steven Rostedt. o Added patch #4.
