If the network is disconnected it is impossible to unmount, even if no
processes are accessing the mount. umount -f and umount -l both hang on
readlink("/home/orion").
umount needs to canonicalize the path so it does a readlink on the path given to
it.
It seems that the canonicalization is unnecessary (already fixed in libmount
upstream code). https://bugzilla.redhat.com/show_bug.cgi?id=820707
That appears to fix the issue for me. Thanks!
This appears to wait forever. This pretty much makes it impossible to use krb5
nfs4 with laptops where the network can disappear.
Is it possible to interrupt this "wait" by signal? ... then we can add alarm()
to critical sections in programs like umount or lsof.
Now for example lsof resolves this problem by fork() and timeout in
parent.. that's pretty nasty solution :-(

Seems unnecessary with the above fix.
