Can't umount floppies/zip in Kernel 2.4.0

I've just upgraded from 2.2.16 to 2.4.0 (after taking care of the upgrades
in the Documentation/Changes file)

I got the following behavior with fdutils (as a non-root user):

---
mixcoac:~> fdmount
fdmount (/dev/fd0): mounted msdos 1440K-disk (read/write) on /fd0


mixcoac:~> fdumount
fdumount (/dev/fd0): failed to unmount: Invalid argument

---


Disk can only be unmounted by root. The mountpoint has the right owner 
(the user) and permissions. Also I've checked /etc/mtab to be ok.


The same occurs to jaZip (an utility to mount/unmount ZIP disks as
non-root user).


If I boot with kernel 2.2.16 everything works ok.


What changed from 2.2 to 2.4? Am I missing something?
