+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.
