In function compress_file_range(), then the compression is finished, the
function just round up @total_in to PAGE_SIZE.

This is fine for regular sectorsize == PAGE_SIZE case, but not for
subpage.

Just change the ALIGN(, PAGE_SIZE) to round_up(, sectorsize) so that
both regular sectorsize and subpage sectorsize will be happy.
