>autofs-5.0.8 - check for existing offset mount before mounting
>
>From: Ian Kent <raven@themaw.net>
>
>The change that introduced the miscellaneous device for autofs
>mount control removed a mount point mounted check from the
>mount_autofs_offset() function for when the miscellaneous
>device is not used.
>
>But a subsequent change that enabled limited update of the exports
>of a hosts mount needed that check. Without it a second occurance
>of the offset (corresponding to an export) could be mounted upon
>a map re-read.
