The immutable and append-only properties on an inode are published on the inode's i_flags and enforced by the VFS. Create a helper to fill the corresponding STATX_ATTR_ flags in the kstat structure from the inode's i_flags. Only orange was converted to use this helper. Other filesystems could use it in the future. Suggested-by: Miklos Szeredi <miklos@szeredi.hu> Signed-off-by: Amir Goldstein <amir73il@gmail.com> Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
