[PATCH review 11/16] procfs: Print task uids and gids in the userns that opened the proc file

[Eric W. Biederman]

From: "Eric W. Biederman" <ebiederm at xmission.com>

Instead of using current_userns() use the userns of the opener
of the file so that if the file is passed between processes
the contents of the file do not change.
