From: Mao Minkai <maominkai@wxiat.com> Sunway inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I56OLG -------------------------------- Use debugfs_create_file() to create debugfs file for tc_sched_clock so it is protected against file removals. Change its name to "tc_sched_clock" to stay consistent with what we use in cmdline.
