Subject: [Qemu-devel] [PATCH 3/3] linux-user: correct timerfd_create syscall numbers
Date: Mon, 15 Feb 2016 16:00:12 +0200	[thread overview]
Message-ID: <1455544812-14403-3-git-send-email-riku.voipio@linaro.org> (raw)

From: Riku Voipio <riku.voipio@linaro.org>

x86, m68k, ppc, sh4 and sparc failed to enable timerfd, because they
didn't have timerfd_create system call defined. Instead Qemu
defined timerfd syscall. Checking with kernel sources, it appears
kernel developers reused timerfd syscall number with timerfd_create,
presumably since no userspace called the old syscall number.
