Are you sure you don't have a pseudo-filesystem mounted on top of
/dev?

What does "df /dev" report.  If it's something like this, you are
using a pseudo-filesystem for /dev:

% df /dev
Filesystem     1K-blocks  Used Available Use% Mounted on
udev               10240     0     10240   0% /dev

In that case, what debugfs is showing is the entries in your /dev
directory before the udev file system is mounted on top of /dev.
