Re: [PATCH] namespaces: introduce sys_hijack (v8)

[Mark Nelson <markn-8fk3Idey6ehBDgjK7y7TUQ@public.gmane.org>]

Hi Serge,

Quick fix (feel free to just fold it into your patch). There may be
a smarter way of fixing this, but this worked for -lxc...

Thanks!

Mark.


ERR_PTR is now used in cgroup code so we need to include err.h

This fixes the build error with CGROUPS disabled:

In file included from include/linux/cpuset.h:14,
                 from mm/slub.c:19:
include/linux/cgroup.h: In function 'task_from_cgroup_fd':
