This looks like a reasonable idea... but a couple of nits...
1) There needs to be an update to the man page, in a separate patch, preferably.
2) Please don't make the patch an email attachment, inline it in
email. See http://www.kernel.org/pub/linux/docs/lkml/#s1-10
for details.
3) Please add the 'Signed-off-by:' line after your patch description.
Note, in the next day or so I will be doing nfs-utils release.
If you are interested in having this patch included please repost
it in a timely matter...
tia,
steved.
