From fa0334f19f0e1a1e570fc2a160dfe53536599ade Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu Date: Thu, 10 May 2007 22:23:08 -0700 Subject: Replace pid_t in autofs with struct pid reference Make autofs container-friendly by caching struct pid reference rather than pid_t and using pid_nr() to retreive a task's pid_t. ChangeLog: - Fix Eric Biederman's comments - Use find_get_pid() to hold a reference to oz_pgrp and release while unmounting; separate out changes to autofs and autofs4. - Fix Cedric's comments: retain old prototype of parse_options() and move necessary change to its caller.
