Mask to apply to leaf qsmask. = Bitmasks in an rcu_node cover the interval [grplo, grphi] of CPU IDs, and* are indexed relative to this interval rather than the global CPU ID space.* This generates the bit for a CPU in node-local masks.(This CPU's leaf of hierarchy , cpu)

WARN_ON_ONCE(Return true if the snapshot returned from rcu_dynticks_snap()* indicates that RCU is in an extended quiescent state.)
