Subject[PATCH -mm 0/2] make /proc/PID/*maps* namespace friendly
Hello,

Lets continue the boring proc/maps cleanups.

Eric, I do agree that the tgid vs pid logic looks strange, but I didn't
even try to change it. Let's at least fix the namespace problems first.
This is minor, but it is shame that /proc/pid/maps still shows the pid
from the global namespace. And this is preparation for the next change.

With this change the only user of proc_maps_private->task is
hold_task_mempolicy/release_task_mempolicy. I believe this code is buggy
and should die, but this needs the changes in mm/mempolicy.c.

After that we can kill priv->task. task_nommu.c can be updated right now,
but it would be better to change it along with task_mmu.c (we have a small
complication with -ESRCH).

Oleg.
