From b073e110e81bc16d17d4d0bcc40f0137685bbf39 Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Fri, 15 Mar 2013 13:15:43 +0000 Subject: blktap2: use sys/eventfd.h if it is available arm64 only has the eventfd2 system call and using the libc wrapper when available hides this from us. eventfd() has been in libc since glibc 2.8. This code is already Linux specific.
