From: "Paul E. McKenney" <paul...@kernel.org> The rtp->tasks_gp_seq grace-period sequence number is not a strict count, but rather the usual RCU sequence number with the lower few bits tracking per-grace-period state and the upper bits the count of grace periods since boot, give or take the initial value. This commit therefore adjusts this comment.
