Looks like sg_init() was fixed for the non-GSS code in "LU-1714 lnet: Properly initialize sg_magic value" http://review.whamcloud.com/3709 but not in the GSS code.

Andrew, could you have a look at this patch http://review.whamcloud.com/#/c/5572/ please? basically I'm trying to remove obsolete capa code on the server side. I looked at your patch and they shouldn't conflict, AFAICS, but probably I missed something.
