I have added two more mailing lists to the Cc.  Please Cc them on any
other patches related to the maple tree and mm area.

This comment isn't clear.

Maybe something like (please, modify it to your liking):
"Since the return value of mas_wr_store_entry() is not used, the return
type can be changed to void"

Please keep this return statement, as you did above, for consistency and
code clarity.
