From a3530df33eb91d787d08c7383a0a9982690e42d0 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Wed, 16 May 2012 15:16:39 -0500 Subject: ceph: have get_authorizer methods return pointers Have the get_authorizer auth_client method return a ceph_auth pointer rather than an integer, pointer-encoding any returned error value. This is to pave the way for making use of the returned value in an upcoming patch.
