From 1e8a9191ccc286bbbfc1f9dccd31ac3bc9ec8a3f Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Fri, 9 Sep 2022 11:17:44 +0200 Subject: f2fs: port to vfs{g,u}id_t and associated helpers A while ago we introduced a dedicated vfs{g,u}id_t type in commit 1e5267cd0895 ("mnt_idmapping: add vfs{g,u}id_t"). We already switched over a good part of the VFS. Ultimately we will remove all legacy idmapped mount helpers that operate only on k{g,u}id_t in favor of the new type safe helpers that operate on vfs{g,u}id_t.
