Yes, sort of...
But you'd potentially end up calling sg_copy_to_buffer multiple times
per page within the sg (given that gnttab_foreach_grant_in_range might
call blkif_copy_from_grant/blkif_setup_rw_req_grant multiple times).
Even calling sg_copy_to_buffer once per page seems rather inefficient as
it uses sg_miter internally.
Switching the for_each_sg to sg_miter is probably the nicer solution as
it takes care of the mapping and the offset/length accounting for you
and will have similar performance.
But, yes, if performance is not an issue, switching it to
sg_copy_to_buffer would be a less invasive change than sg_miter. Which
the same might be said about a lot of these cases.
Unfortunately, changing from kmap_atomic (which is a null operation in a
lot of cases) to sg_copy_X_buffer is a pretty big performance hit.
