It sort of feels like that `rc' is not needed there at all. It's being used in
rc = ksmbd_vfs_set_dos_attrib_xattr(user_ns,
filp->f_path.dentry, &da);
if (rc)
ksmbd_debug(SMB,
"failed to restore file attribute in EA\n");
and in
rc = setattr_prepare(user_ns, dentry, &attrs);
if (rc)
return -EINVAL;
Either it should be used more, and probably be a return value, or we can
just remove it.
