Hi all,

looks like there is a bug in Busybox mountpoint:

$ mkdir m r
$ mount -obind m r
$ touch m/a touch m/b
$ ls m/
a b
$ ls r/
a b
$ mountpoint r
r is a mountpoint
$ busybox mountpoint
r is not a mountpoint     !!!

Looks that Busybox mountpoint ignore via bind mounted directories and
illegally report them as not being a mounted point. Did not dig into
source, just detected that bug.
