From d9edfc5a4f81165e64d4ad6e423a8554c88dd0de Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Tue, 18 Apr 2017 12:03:39 +0300 Subject: [PATCH] IB/core: Nullify ib_uobject during allocation Currently, we initialize all fields of ib_uobject straight after allocation. Therefore, a kmalloc was sufficient. Since ib_uobject could be embedded in a type specific structure, we nullify it to spare programmer errors.
