Subject: rcu: Fix obsolete priority-boosting comment
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bc17ea1092c48227334a311a130c1a41966333fe;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

rcu: Fix obsolete priority-boosting comment

Tasks are no longer migrated to the root rcu_node, so there is no
longer any need for a boost kthread for the root rcu_node, and there no
longer is such a kthread.  This commit therefore fixes the comment in
rcu_boost_kthread()'s header to reflect this new reality.
