Ian Kent 051d381259 [PATCH] autofs4: nameidata needs to be up to date for follow_link 
In order to be able to trigger a mount using the follow_link inode method the
nameidata struct that is passed in needs to have the vfsmount of the autofs
trigger not its parent.

During a path walk if an autofs trigger is mounted on a dentry, when the
follow_link method is called, the nameidata struct contains the vfsmount and
mountpoint dentry of the parent mount while the dentry that is passed in is
the root of the autofs trigger mount.  I believe it is impossible to get the
vfsmount of the trigger mount, within the follow_link method, when only the
parent vfsmount and the root dentry of the trigger mount are known.

This patch updates the nameidata struct on entry to __do_follow_link if it
detects that it is out of date.  It moves the path_to_nameidata to above
__do_follow_link to facilitate calling it from there.  The dput_path is moved
as well as that seemed sensible.  No changes are made to these two functions.
