From ca47ba3119365eafac0ab25a86cab9d9a1b29bd4 Mon Sep 17 00:00:00 2001
From: Sam James <sam@gentoo.org>
Date: Sat, 30 Sep 2023 06:38:53 +0100
Subject: [PATCH] test: handle POSIX ioctl prototype
glibc has the following prototype for ioctl: int ioctl(int fd, unsigned long request, ...)
POSIX (inc. musl) has the following for ioctl: int ioctl(int fd, int request, ...)
Check which prototype is used in <sys/ioctl.h> to avoid a conflict and conditionally
define the right one for the system.
Bug: https://bugs.gentoo.org/914921
Signed-off-by: Sam James <sam@gentoo.org>
Upstream-Status: Backport [https://github.com/linux-nvme/libnvme/commit/ca47ba3119365eafac0ab25a86cab9d9a1b29bd4]
