Subject: mas_wr_split() Avoid mas_wr_new_end() call
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=cc157b884236cac40c1d0a61e5fc54f31b1928eb;p=users%2Fjedix%2Flinux-maple.git

mas_wr_split() Avoid mas_wr_new_end() call

ma_part has the size set to what is needed by examining the same data.
Use ma_part.size instead.
