Question:I was following the lab video and I was unsure on how to set the footer for the free block. Also, I am unsure about whether my masking for my allocated block is correct and if interpreted the professor correctly. Any suggestions would be greatly appreciated, thank you

So the footer is going to be used to make coalescing possible. It should be at the end of a block, so the next block could use it to get to the header tags. You have to use UNSCALED_POINTER_ADD to get to the near of the end of the block and then write there. 
I didn't get your second question. Could you clarify it, please?

Hi,

Thank you, I understand how to make the footer work now. It will basically also have same data as the header. My second question was relating to my code in line 447, I tried to follow lab 9 instr, but I'm not sure if I have grasped it correctly. So I was looking forward to some suggestions. Thanks a lot

I think in your new commit the line number has been changed.
