Browse Source 
$ tools/perf/trace/beauty/move_mount_flags.sh
  static const char *move_mount_flags[] = {
	  [ilog2(0x00000001) + 1] = "F_SYMLINKS",
	  [ilog2(0x00000002) + 1] = "F_AUTOMOUNTS",
	  [ilog2(0x00000004) + 1] = "F_EMPTY_PATH",
	  [ilog2(0x00000010) + 1] = "T_SYMLINKS",
	  [ilog2(0x00000020) + 1] = "T_AUTOMOUNTS",
	  [ilog2(0x00000040) + 1] = "T_EMPTY_PATH",
  };
  $
