From bcf58e725ddc45d31addbc6627d4f0edccc824c1 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 26 Jul 2012 04:02:49 -0700 Subject: userns: Make create_new_namespaces take a user_ns parameter Modify create_new_namespaces to explicitly take a user namespace parameter, instead of implicitly through the task_struct. This allows an implementation of unshare(CLONE_NEWUSER) where the new user namespace is not stored onto the current task_struct until after all of the namespaces are created.
