Hi,
I'm not sure that this one is a correct list to report such a bug. I
experience a weird issue and I'm not sure whether it's a bug or a
feature. :)
I'm connecting a fedora core 3 (i.e. 2.6.9) client to a sles9 (i.e.
2.6.5) server. Once I perform the following (completely legal) steps,
I'm unable to unmount the disk that was once exported.

1) at the server: mount /dev/sdag1 /tmp/export
2) at the server: exportfs "*:/tmp/export"  -o "rw" #note that this
export is not at the /etc/exports
3) at the client: mount server:/tmp/export /tmp/mountpoint
4) at the client: ls /tmp/mountpoint         #or some other usage
5) at the client: unexport /tmp/mountpoint
6) at the server: exportfs -r			# removes the export, as it is not in
the /etc/exports
7) at the server: umount /dev/sdag1		#fails, though noone uses it.
It looks like that the exportfs -r somehow fails to decrement the usage
count on the block device.


As a totally separate issue, I fail to figure out a conditions, when a
client sends a READDIR instead of a READDIR+. I've found in the sources,
that it happens once a directory size is bigger than 8 pages, but I
tried to gradually remove files to the directory at the server and
failed to return from READDIR to READDIR+.
