| |
Hello!
This series fixes a brown-paper-bag NMI self-deadlock bug located by Thomas Gleixner and adds comments:
1. Don't acquire lock in NMI handler in rcu_nmi_enter_common().
2. Add comments marking transitions between RCU watching and not.
These pass light rcutorture testing, and seem like v5.8 material.
Thanx, Paul
