Subject: [PATCH 0/6] autofs: misc patches

This series contains several patches that resulted mostly from comments
made by Al Viro (quite a long time ago now).

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.
