Re: [PATCH -next] orangefs: use vzalloc() instead of vmalloc()/memset(0)

Wei...

I have applied your patch and tested it, it seems good.

The gossip statement still references vmalloc, I used
"git commit --amend" to fix that for my test. I'll do the
same when I push to kernel.org too, if you're OK with that,
unless you want to fix it yourself and resend the patch...

Thanks!
