OT: mount/umount doesn't track used resources correctly?

OT: mount/umount doesn't track used resources correctly?

[Miles Lane]

I am having trouble removing the usbide module
which enables me to access my USB external 
hard drive.  I think the problem may be due
to usermode tools not handling the new "mount
multiple devices to a single mount point" feature,
but I'm not sure.

Here was my mount configuration for /dev/pda 
devices (the partitions on my USB BusLink drive)
before I unmounted all these partitions:

/dev/pda8              2016016        20   1913584   0% /mnt/pda8
/dev/pda8              2016016        20   1913584   0% /mnt/pda9
/dev/pda9              2016016        20   1913584   0% /mnt/pda9

Currently, mount shows:

/dev/hda7 on / type ext2 (rw)
none on /proc type proc (rw)
none on /dev/pts type devpts (rw,mode=0620)
/dev/hda8 on /home type ext2 (rw)
/dev/hda1 on /mnt/Win98 type vfat (rw,nosuid,nodev,umask=0)
none on /proc/bus/usb type usbdevfs (rw)

Any ideas?

Yes, quite possibly.  Rumor has it that util-linux has recently
acquired some wisdom in this area.  (I can't confirm or deny.)  Try
upgrading, or just trust /proc/mounts for the real story..

Woohoo!  Thanks Peter.

You are correct.  I just built and installed util-linux-2.10s
from source.  I ran through the cross-mounting scenario
and was able to unmount all the partitions on the USB
external drive and then unload all the USB drivers.

Perhaps util-linux-2.10s should be made the new default
listed in Documentation/Changes?

Cheers,
