From 6ce315234aefcbc599dea390c15672156ebf9e7b Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 11 Oct 2006 01:22:15 -0700 Subject: [PATCH] AUTOFS: Make sure all dentries refs are released before calling kill_anon_super() Make sure all dentries refs are released before calling kill_anon_super() so that the assumption that generic_shutdown_super() can completely destroy the dentry tree for there will be no external references holds true. What was being done in the put_super() superblock op, is now done in the kill_sb() filesystem op instead, prior to calling kill_anon_super(). This makes the struct autofs_sb_info::root member variable redundant (since sb->s_root is still available), and so that is removed. The calls to shrink_dcache_sb() are also removed since they're also redundant as shrink_dcache_for_umount() will now be called after the cleanup routine.
