From d15b621168c7c422b8e43819c45aa749f3611fa6 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 2 Dec 2020 12:57:28 +0100 Subject: [PATCH 126/323] sched/cputime: Remove symbol exports from IRQ time accounting Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz account_irq_enter_time() and account_irq_exit_time() are not called from modules. EXPORT_SYMBOL_GPL() can be safely removed from the IRQ cputime accounting functions called from there.
