Wouldn't this make it harder to fix the regression when swap file support was temporarily removed from cifs.ko (due to the folio migration)? I was hoping to come back to fixing swapfile support for cifs.ko in 6.10-rc (which used to pass the various xfstests for this but code got removed with folios/netfs changes). -----Original Message----- From: Kairui Song <ryncsn@xxxxxxxxx> Sent: Monday, April 29, 2024 2:05 PM To: linux-mm@xxxxxxxxx Cc: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>; Huang, Ying <ying.huang@xxxxxxxxx>; Matthew Wilcox <willy@xxxxxxxxxxxxx>; Chris Li <chrisl@xxxxxxxxxx>; Barry Song <v-songbaohua@xxxxxxxx>; Ryan Roberts <ryan.roberts@xxxxxxx>; Neil Brown <neilb@xxxxxxx>; Minchan Kim <minchan@xxxxxxxxxx>; Hugh Dickins <hughd@xxxxxxxxxx>; David Hildenbrand <david@xxxxxxxxxx>; Yosry Ahmed <yosryahmed@xxxxxxxxxx>; linux-fsdevel@xxxxxxxxxxxxxxx; linux-kernel@xxxxxxxxxxxxxxx; Kairui Song <kasong@xxxxxxxxxxx>; Steven French <Steven.French@xxxxxxxxxxxxx>; Namjae Jeon <linkinjeon@xxxxxxxxxx>; Paulo Alcantara (SUSE) <pc@xxxxxxxxxxxxx>; Shyam Prasad <Shyam.Prasad@xxxxxxxxxxxxx>; Bharath S M <bharathsm@xxxxxxxxxxxxx> Subject: [EXTERNAL] [PATCH v3 05/12] cifs: drop usage of page_file_offset [Some people who received this message don't often get email from ryncsn@xxxxxxxxx. Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ] From: Kairui Song <kasong@xxxxxxxxxxx> page_file_offset is only needed for mixed usage of page cache and swap cache, for pure page cache usage, the caller can just use page_offset instead. It can't be a swap cache page here, so just drop it and convert it to use folio.
