From 794933b38354a2612cf2c471f11798b306f35315 Mon Sep 17 00:00:00 2001
From: Jan Stancek <jstancek@redhat.com>
Date: Mon, 20 May 2019 20:47:20 +0200
Subject: [PATCH] shmctl01: don't use hardcoded index == 0 for SHM_STAT test
Test fails on SHM_STAT testcase:
shmctl01 5 TFAIL : shmctl01.c:173: shmctl01 call failed
errno = 22 : Invalid argument
shmctl(0, SHM_STAT, 0x601060) = -EINVAL
since following commit:
commit 99db46ea292780cd978d56932d9445b1e8bdafe8
Author: Manfred Spraul <manfred@colorfullife.com>
Date: Tue May 14 15:46:36 2019 -0700
ipc: do cyclic id allocation for the ipc object.
Don't rely on index 0 being always available, but instead
use (maximum) index returned by SHM_INFO.
