Subject: autofs4: autofs4_follow_link false negative fix
From: Ian Kent <raven@xxxxxxxxxx>
The check for an empty directory in the autofs4_follow_link method fails
occassionally due to old dentrys. We had the same problem
autofs4_revalidate ages ago. I thought we wouldn't need this in
autofs4_follow_link, silly me.
