rcu: Inline rcu_kthread_do_work() into its sole remaining caller (c46f497a) · Commits · 戴 / test

The rcu_kthread_do_work() function has a single-line body and only one remaining caller. This commit therefore saves a few lines of code by inlining rcu_kthread_do_work() into its sole remaining caller. Signed-off-by:
