If anyone has any objections, please let me know. ------------------ From: Ian Kent commit 49999ab27eab6289a8e4f450e148bdab521361b2 upstream. 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).
