If Sphinx needs to know about that, then fine. OTOH, for scripts/kernel-doc,
a similar change could have been made to dump_struct(), along with these
others:

	# strip attributes
	$members =~ s/\s*$attribute/ /gi;
	$members =~ s/\s*__aligned\s*\([^;]*\)/ /gos;
	$members =~ s/\s*__packed\s*/ /gos;
	$members =~ s/\s*CRYPTO_MINALIGN_ATTR/ /gos;
	$members =~ s/\s*____cacheline_aligned_in_smp/ /gos;
	$members =~ s/\s*____cacheline_aligned/ /gos;
