Andrew might add this to mm.git while fixing the checkpatch warning on his own.
Let's give time for Andrew today.

I also added this to damon/next tree after fixing the warning.  If Andrew
doesn't pick this with the fix today, I will post mine as v2 of this patch
tomorrow.  If you prefer to do the v2 posting on your own, just let me know :)


Thanks,
SJ
