can't read superblock in a infinite " mount/umount" loop

[Le Rouzic]

Hi,

Using Linux version 2.6.18-rc6-CITI_NFS4_ALL-1 but it happens also with
previous versions like 2.6.17-rc2, 
we got quickly
 "can't read superblock"
by running an infinite mount/umount loop

while true
do
mount /mnt/nosec
date
umount /mnt/nosec
done

The issue is registered in bugzilla at:

  http://developer.osdl.org/dev/nfsv4/bugzilla/show_bug.cgi?id=128  
  

Best regards
