Bug#669314: trailing slash on nfsvers=2,3 mounts

[laurent+debian@u-picardie.fr]

Hi,

I've been able to reproduce this bug.
It doesn't happen when using nfs4, it does with nfsvers=2 or
nfsvers=3.

I can reproduce it with:
ii  linux-image-3.2.0-2-amd64          3.2.15-1
ii  libmount1                          2.20.1-4
ii  mount                              2.20.1-4
ii  nfs-common                         1:1.2.5-4

and it's still reproducible with linux-image 3.3.2-1~experimental.1
and also with previous version of mount (2.20.1-1.2) and nfs-commont
(1:1.2.5-3)

Another information, i'm booting from nfs, for the purpose of this
bug report I've booted with init=/bin/sh

$ cat /proc/cmdline
console=hvc0
ip=10.20.30.14:10.20.30.241::255.255.255.0:log-01:eth0:off
nfsroot=10.20.30.241:/vol/nfsroot/log-01 boot=nfs root=/dev/nfs rw init=/bin/sh

$ grep nfsroot /proc/mounts
10.20.30.241:/vol/nfsroot/log-01/ / nfs
rw,relatime,vers=3,rsize=65536,wsize=65536,namlen=255,hard,nolock,proto=tcp,port=65535,timeo=7,retrans=10,sec=sys,local_lock=all,addr=10.20.30.241
