Subject: [PATCH v5 07/12] netfs: drop usage of folio_file_pos
From: Kairui Song <kasong@...cent.com>
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 netfs. So just drop
it and use folio_pos instead.
