H A D | checksum.h | 594e450b Sat Jun 05 09:19:30 CDT 2021 Al Viro <viro@zeniv.linux.org.uk> csum_and_copy_to_iter(): massage into form closer to csum_and_copy_from_iter()
Namely, have off counted starting from 0 rather than from csstate->off. To compensate we need to shift the initial value (csstate->sum) (rotate by 8 bits, as usual for csum) and do the same after we are finished adding the pieces up.
What we get out of that is a bit more redundancy in our variables - from is always equal to addr + off, which will be useful several commits down the road.
