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

From: Eric W. Biederman
Date: Mon Nov 19 2012 - 10:17:42 EST


From: "Eric W. Biederman" <ebiederm@xxxxxxxxxxxx>

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.
