From c7b96acf1456ef127fef461fcfedb54b81fecfbb Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 20 Mar 2013 12:49:49 -0700 Subject: userns: Kill nsown_capable it makes the wrong thing easy nsown_capable is a special case of ns_capable essentially for just CAP_SETUID and CAP_SETGID. For the existing users it doesn't noticably simplify things and from the suggested patches I have seen it encourages people to do the wrong thing. So remove nsown_capable.
