perf beauty: Add generator for 'move_mount' flags argument
$ 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",
};
$
Will be wired up to the 'perf trace' arg in a followup patch.
