My problem is a bit different.

"mount -t nfs4 server:export /mnt" works but umount fails.

Notice that there is no '/' in the path!

Normalizing or just stripping leading '/'s early won't help with the
above problem and since there is already a hack to strip the
__trailing__ '/' that kernel adds to /proc/mounts file, I just made the
existing hack it a bit better by normalizing.
