Missing changelog ... and Signed-off-by should use your real identity,
not a handle :)

checkpatch.pl is your friend, please run it next time :)

Already fixed in mm-new:

This one as well:

So this patch is stale now: all three hunks are already covered in
mm-new.

Thank you for checking this, Lance!

I also double confirm the typos in DAMON docs are already fixed in mm.git.

I also double checked this.  Lance is correct.
