[REVIEW][PATCH 00/11] userns: Simple filesystems conversions

This continus my conversion of filesystems to support running
when kernel user namespace supprot is enabled.  This time I have
targed the filesystems that I had to look twice at to verify
the changes were correct.

The strategy is to convert the structures in the kernel where we store
uid_t and gid_t to to kuid_t and kgid_t.  To assume all file systems are
encoded in the initial user namespace for purposes of conversions.
Mount options containing uids and gids along with other user space
interfaces are of assumed to be encoded in the current user namespace.

These patches are against:
