Subject: rcu: Remove exports from rcu_idle_exit() and rcu_idle_enter()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=16c0b106070f4760f7d1fffb0cd40393552b5294;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

rcu: Remove exports from rcu_idle_exit() and rcu_idle_enter()

The rcu_idle_exit() and rcu_idle_enter() functions are exported because
they were originally used by RCU_NONIDLE(), which was intended to
be usable from modules.  However, RCU_NONIDLE() now instead uses
rcu_irq_enter_irqson() and rcu_irq_exit_irqson(), which are not
exported, and there have been no complaints.

This commit therefore removes the exports from rcu_idle_exit() and
rcu_idle_enter().
