[PATCH rcu 06/13] rcu-tasks: Move RTGS_WAIT_CBS to beginning of rcu_tasks_kthread() loop

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Early in debugging, it made some sense to differentiate the first
iteration from subsequent iterations, but now this just causes confusion.
This commit therefore moves the "set_tasks_gp_state(rtp, RTGS_WAIT_CBS)"
statement to the beginning of the "for" loop in rcu_tasks_kthread().
