[Qemu-devel] problem with loop device

I'm running on CentOS4 with a 2.6.11 kernel.  After using losetup to
configure loop0 and mounting /dev/loop0, I am unable to unmount it.  I keep
getting "device is busy" message, but lsof doesn't show anything.
Everything is being built automatically by a script, so I know I'm not
leaving a terminal session using it as a working directory.  Any ideas?

Use fuser -m to figure out what's still using the mount.
Make sure you don't have any other filesystems mounted inside it.

Nothing shows up as still using the mount.  Any other ideas?

is loop device support compiled in the kernel ?
