From e44fcb4b7a299602fb300b82a546c0b8a50d9d90 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 16 Oct 2019 04:56:54 +0200 Subject: sched/vtime: Rename vtime_accounting_cpu_enabled() to vtime_accounting_enabled_this_cpu() Standardize the naming on top of the vtime_accounting_enabled_*() base. Also make it clear we are checking the vtime state of the *current* CPU with this function. We'll need to add an API to check that state on remote CPUs as well, so we must disambiguate the naming.
