Hi guys, I'm wondering if there is any pitfalls when mixing the legacy page based code with higher order (order >= 1) folios. E.g. if I allocated a folio with order 2, attached some private data to the folio, then call filemap_add_folio(). Later some one called find_lock_page() and hit the 2nd page of that folio. I believe the regular IO is totally fine, but what would happen for the page->private of that folio? Would them all share the same value of the folio_attach_private()? Or some different values? Thanks, Qu
