Subject[PATCH tip/core/rcu 0/3] Documentation updates for 4.2
Hello!

This series provides a few documentation updates:

1. Fix description of smp_mb__before_spinlock() semantics, courtesy
of Will Deacon.

2. Add another caveat to the list regarding the care and feeding
of pointers returned by rcu_derefence(). You cannot let the
compiler know too much.

3. Explicitly state that each instance of rcu_dereference() will
reload the pointer, courtesy of Milos Vyletel.

Thanx, Paul
