------------------------------------------------------
Subject: bsdacct: account dying tasks in all relevant namespaces
From: Pavel Emelyanov <xemul@xxxxxxxxxx>

This just makes the acct_proces walk the pid namespaces from current up to
the top and account a task in each with the accounting turned on.

ns->parent access if safe lockless, since current it still alive and holds
its namespace, which in turn holds its parent.
