From bcd0f3ef964aead4b9e95c10f4c5c75f58ba102c Mon Sep 17 00:00:00 2001
From: "Dmitry V. Levin" <ldv@strace.io>
Date: Mon, 15 Mar 2021 08:00:00 +0000
Subject: [PATCH 146/149] tests: use xasprintf instead of asprintf
* tests/clone-flags.c: Include "xmalloc.h", replace all asprintf
invocations followed by perror_msg_and_fail with xasprintf.
* tests/epoll_pwait2.c: Likewise.
* tests/faccessat.c: Likewise.
* tests/faccessat2.c: Likewise.
* tests/ioctl_kvm_run_common.c: Likewise.
* tests/keyctl.c: Likewise.
* tests/lock_file.c: Likewise.
* tests/mq.c: Likewise.
* tests/mq_sendrecv.c: Likewise.
* tests/netlink_protocol.c: Likewise.
* tests/old_mmap.c: Likewise.
* tests/tracer_ppid_pgid_sid.c: Likewise.
