[PATCH] autofs4: panic after mount fail
Resolve the panic on failed mount of an autofs filesystem originally reported by Mao Bibo. It addresses two issues that happen after the mount fail. The first a NULL pointer reference to a field (pipe) in the autofs superblock info structure and second the lack of super block cleanup by the autofs and autofs4 modules.
