(I thought briefly of looking for an existing implementation but
then chose not to since I wanted to minimize the functional changes in my 
patches
for the time being. Additionally I was wary of using a different implementation 
for a
division operation.)

I'll submit a patch that will replace the local implemetaion of rounded
division with the in-kernel implementation (I'm assuming you're
referring to the DIV_ROUND_CLOSEST macro from include/linux/kernel.h).

Thanks
