From 3d3653f9732c73feb8c4addfc1cbdaa292a399fa Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 12 Jul 2017 14:35:22 -0700 Subject: ipc: move atomic_set() to where it is needed Only after ipc_addid() has succeeded will refcounting be used, so move initialization into ipc_addid() and remove from open-coded *_alloc() routines.
