Eric W. Biederman 87bfbf679f [PATCH] proc: Simplify the ownership rules for /proc 
Currently in /proc if the task is dumpable all of files are owned by the tasks
effective users.  Otherwise the files are owned by root.  Unless it is the
/proc/<tgid>/ or /proc/<tgid>/task/<pid> directory in that case we always make
the directory owned by the effective user.

However the special case for directories is pointless except as a way to read
the effective user, because the permissions on both of those directories are
world readable, and executable.

/proc/<tgid>/status provides a much better way to read a processes effecitve
userid, so it is silly to try to provide that on the directory.

So this patch simplifies the code by removing a pointless special case and
gets us one step closer to being able to remove the hard coded /proc inode
numbers.
