From e999a5c5a19cf3b679f3d93c49ad5f5c04e4806c Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Fri, 24 Mar 2023 18:01:01 +0000 Subject: fs: Add FGP_WRITEBEGIN This particular combination of flags is used by most filesystems in their ->write_begin method, although it does find use in a few other places. Before folios, it warranted its own function (grab_cache_page_write_begin()), but I think that just having specialised flags is enough. It certainly helps the few places that have been converted from grab_cache_page_write_begin() to __filemap_get_folio().
