2.6.24-rc3 unable to mount something which should use nohide

[Eric Paris <eparis@redhat.com>]

NFS server "paris" (some 2.6.18 based kernel):

[root@paris ~]# mount | grep storage
/dev/mapper/StorageVG01-LogVol00 on /export/storage type ext3 (rw)
/dev/mapper/KernelVG01-LogVol00 on /export/storage/kernel type ext3 (rw)
[root@paris ~]# cat /etc/exports
/export/storage         *(rw,sync,all_squash,anonuid=500,anongid=500)
/export/storage/kernel  *(rw,sync,all_squash,anonuid=500,anongid=500,nohide)

On my clients x86_64 running an almost clean-from-git 2.6.24-rc3 kernel:

[root@dhcp231-145 ~]# mount -o noatime paris:/export/storage /storage
[root@dhcp231-145 ~]# ls /storage/kernel
ls: cannot access /storage/kernel: Stale NFS file handle

(notice /storage/kernel should be triggering that nohide mount
for /export/storage/kernel) so I figured maybe that automatic nohide
stuff was broken.  I'll try by hand:

[root@dhcp231-145 ~]# mount paris:/export/storage/kernel /storage/kernel
mount.nfs: Stale NFS file handle

Same thing.  Nothing in dmesg or /var/log/messages.  I know this worked
not long ago....
