They are: - make use of the .permission() method for access checks. - use dentry info count instead of simple_empty() to avoid taking a spinlock. - add a use cases comment to autofs_mountpoint_changed(). - make better use of mount trigger flags (I think this was actually mentioned by me at the time). Others: - fix usage consistency problem with dentry info count. - remove unused inode field from info struct.
