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
