[PATCH] switch autofs4 to touch_atime()
After my lookup_hash patch ->d_revalidate always gets a valid struct nameidata passed (unless you use lookup_one_len which autofs4 doesn't), so we can switch it from update_atime to touch_atime. This is a bit of an academic excercise because autofs has a 1:1 vfsmount superblock relation, but I want to get rid of update_atime so filesystems authors can't easily screw up per-mountpoint noatime support.
