From f76baf9365bd66216bf0e0ebfc083e22eda6215b Mon Sep 17 00:00:00 2001 From: Alexander Krizhanovsky Date: Fri, 9 Sep 2005 13:01:59 -0700 Subject: [PATCH] [PATCH] autofs: fix "busy inodes after umount..." This patch for old autofs (version 3) cleans dentries which are not putted after killing the automount daemon (it's analogue of recent patch for autofs4).
