Re: [PATCH] coccinelle: merge two rules from flex_alloc.cocci

Hi Markus,

Thanks for the contribution.

I see that you've sent many Coccinelle patches to the mailing list. It
might be better to send them all together as a single threaded patchset
so that reviewers will have an easier time finding all of them.

None of our other cocci scripts have rulenames so I would drop the
rulename here. It also doesn't really help since its name is so generic.

I would also echo this for the other patches you've sent.

Small nitpick but to be inline with how the rest of our cocci scripts
are written, I'd write this as

	  (x, name, str
	- , strlen(str)
	  );

Thanks,
