>autofs4 - fix reset pending flag on mount fail
>
>From: Ian Kent <raven@themaw.net>
>
>In autofs4_d_automount(), if a mount fail occurs the AUTOFS_INF_PENDING
>mount pending flag is not cleared.
>
>One effect of this is when using the "browse" option, directory entry
>attributes show up with all "?"s due to the incorrect callback and
>subsequent failure return (when in fact no callback should be made).
