From: Kairui Song <kasong@xxxxxxxxxxx> folio_file_pos is only needed for mixed usage of page cache and swap cache, for pure page cache usage, the caller can just use folio_pos instead. It can't be a swap cache page here. Swap mapping may only call into fs through swap_rw and that is not supported for afs. So just drop it and use folio_pos instead.
