Subject: rcu: Inline rcu_kthread_do_work() into its sole remaining caller
X-Git-Tag: v5.15~6906^2^2~11
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c46f497a6151d48cb341e18fdd4dff345f7d253d;p=platform%2Fkernel%2Flinux-starfive.git

rcu: Inline rcu_kthread_do_work() into its sole remaining caller

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.
