-Subject: [PATCH] syscall: don't fail if __NR_signalfd is not defined
-
-lxc fails to build if __NR_signalfd is not defined since version 4.0.0
-and
-https://github.com/lxc/lxc/commit/bed09c9cc0bec7bbd2442fcce4a2a0f03994cb09
-
-However, some architectures don't define __NR_signalfd but only
-__NR_signalfd4. This is the case for example for nios2 or csky:
