Subject: Re: [PATCH] nfs: removed goto statement

Thanks for the link.
I think that goto is really useful and makes a lot of sense when there
are different parts in the function where you want to go to the exit
block.

I think this function is not one of those cases since there's only one
exit point and the goto can be easily removed, in my case 3rd try :)
Maybe at some point, this function had different parts in the code
where it went to the "out" block. But not anymore.

However, I don´t have a strong opinion on this patch. If it's accepted
that's great but mostly I wanted to learn the process of how to
contribute to the kernel and I did it!

Thanks,
Javier
