Since we cannot set these attributes we should special-case the

Er...  So why not simply sanity-check it in places that set it on
inodes?  If anything, I would suggest
	* converting all places that set those in ->i_flags to
inode_set_flags()
	* making inode_set_flags() check and return an error on
that...
