JIRA: https://issues.redhat.com/browse/RHEL-33888 Status: Linus Conflicts: For consistency drop btrfs hunks because it isn't supported in CentOS Stream and other backports also drop such hunks. commit 8782a9aea3ab4d697ad67d1f8ebca38a4e1c24ab Author: Christian Brauner <brauner@kernel.org> Date: Fri Jan 13 12:49:21 2023 +0100 fs: port ->fileattr_set() to pass mnt_idmap Convert to struct mnt_idmap. Last cycle we merged the necessary infrastructure in 256c8aed2b42 ("fs: introduce dedicated idmap type for mounts"). This is just the conversion to struct mnt_idmap. Currently we still pass around the plain namespace that was attached to a mount. This is in general pretty convenient but it makes it easy to conflate namespaces that are relevant on the filesystem with namespaces that are relevent on the mount level. Especially for non-vfs developers without detailed knowledge in this area this can be a potential source for bugs. Once the conversion to struct mnt_idmap is done all helpers down to the really low-level helpers will take a struct mnt_idmap argument instead of two namespace arguments. This way it becomes impossible to conflate the two eliminating the possibility of any bugs. All of the vfs and all filesystems only operate on struct mnt_idmap.
