Hello!

This series contains RCU CPU stall-warning changes for v6.13:

1.	Delete unused rcu_gp_might_be_stalled() function.

2.	Stop stall warning from dumping stacks if grace period ends.

3.	Finer-grained grace-period-end checks in rcu_dump_cpu_stacks().

Changes since v1:

o	Add data_race() to grace-period sequence-number access per
	feedback from Joel Fernandes.

o	Add Reviewed-by tags.

						Thanx, Paul
