[PATCH review 0/6] miscelaneous user namespace patches
Now that I have done my worst to infect user space with some basic tools for using user namespaces, this is my first round of patches aimed at the 3.9 merge window. This documents that if you care about limit resources you want to configure the memory control group when user namespaces are enabled. This enables the user namespace root to mount devpts, ramfs and tmpfs. Functionality that is needed for practical uses of the user namespace. This includes my patch to enable more flexibility into the input allowed in uid_map and gid_map.
