exportfs: Messages indicating unsupported operation that works

[Tony Asleson <tasleson@redhat.com>]

When I try to export a directory that has a space in it I get the following:

# exportfs *:"/mnt/has space"
exportfs: /mnt/has space does not support NFS export

exit code is 0.

If I do:

# exportfs -v
/mnt/has space	<world>(ro,wdelay,root_squash,no_subtree_check,
sec=sys,ro,secure,root_squash,no_all_squash)

It exists and I can mount it from a client and everything appears fine.

I took a peek at the code and we are failing in test_export.  We are
getting a -1 returned when we write to: /proc/net/rpc/nfsd.export/channel .

This seems like a confusing message when it appears that everything is
working, thoughts?

Notes:
- Kernel Linux rawhide 3.13.0-0.rc3.git1.2.fc21.x86_64
- nfs-utils: Latest from git, but this happens on older released
versions tested too.

Thanks,
Tony
