Can you please describe in more detail what is this patch fixing?
In original dump_space_info(), free space info is calculated by
info->total_bytes - info->bytes_used - info->bytes_pinned -
info->bytes_reserved - info->bytes_readonly,
but I think free space info should also minus info->bytes_may_use :)
