Subject[PATCH tip/core/rcu 0/2] Signal-related changes for 3.19
Hello!

This series updates RCU handling in signals:

1. Prevents a possible very long RCU read-side critical section
in kill_pid_info().

2. Explain why the "obviously buggy" freeing of sighand by
__cleanup_sighand() without an RCU grace period really isn't
buggy, courtesy of Oleg Nesterov.

Thanx, Paul
