Analyze and fix the following issue in the Linux kernel code: Revert "[PATCH] Fix d_path for lazy unmounts"
Problem Details: This reverts commit eb3dfb0cb1f4a44e2d0553f89514ce9f2a9fcaf1. It causes some strange Gnome problem with dbus-daemon getting stuck, so we'll revert it until that problem is understood.

Problem Details: The code to look at tty_old_pgrp and send SIGHUP and SIGCONT when it is present only executes when disassociate_ctty is called from do_exit. Make this clear by adding an explict on_exit check, and explicitly setting tty_old_pgrp to 0. In addition fix the locking by reading tty_old_pgrp under the sigl...
