x86/mce: Rename rcu_dereference_check_mce() to mce_log_get_idx_check() The "rcu_" prefix misleads for it being a proper RCU interface which is not. It basically checks whether we're preemptible or holding the chrdev_read mutex. Rename it accordingly. Signed-off-by: Borislav Petkov <b...@suse.de> Acked-by: Paul E.
