From 6651149371b842715906311b4631b8489cebf7e8 Mon Sep 17 00:00:00 2001 From: Ian Kent Date: Fri, 14 Jan 2011 18:46:24 +0000 Subject: [PATCH] autofs4: Clean up autofs4_free_ino() When this function is called the local reference count does't need to be updated since the dentry is going away and dput definitely must not be called here. Also the autofs info struct field inode isn't used so remove it.
