From cbf24edbb3123e3154ad2366912e0c1270ad3546 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Netto Date: Wed, 21 Sep 2022 10:51:06 -0300 Subject: rt: Initialize mq_send input on tst-mqueue{5,6} GCC with -Os warns that the mq_send input may be used uninitialized. Although for the tests the data content sent is not important, since both tests checks only if mq_notify was properly set, the warning is correct and data is indeed uninitialized. Checked on x86_64-linux-gnu and i686-linux-gnu.
