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 ------------------------------------------------------------------------ tree.c | 31 ++++++++++++++++++++++++++----- 1 file changed, 26 insertions(+), 5 deletions(-)
