+Subject: [PATCH] nsexec: fix build against musl libc
+
+Remove a wrongly added include which was added in commit 3c2e77ee (Add a
+compatibility header for CentOS/RHEL 6, 2016-01-29) apparently to
+fix this compile error on centos 6:
+
+> In file included from
+> Godeps/_workspace/src/github.com/opencontainers/runc/libcontainer/nsenter/nsexec.c:20:
+> /usr/include/linux/netlink.h:35: error: expected specifier-qualifier-list before 'sa_family_t'
+
+The glibc bits/sockaddr.h says that this header should never be included
+directly[1]. Instead, sys/socket.h should be used.
+
+The problem was correctly fixed later, in commit 394fb55 (Fix build
+error on centos6, 2016-03-02) so the incorrect bits/sockaddr.h can
+safely be removed.
+
+This is needed to build musl libc.
+
+Fixes #761
