Hmm. That ones seems to be restricted for some reason. I think that this happens when we get escalated bugzillas from customers.

The server side patch isn't quite sufficient on its own. A RHEL-4 patch is also required for the client side. I could construct the RHEL-4 patch so that it alone would be sufficient to address the particular problem that that customer is having, but that isn't the entire situation. Non-Linux clients would still have a problem with the current upstream Linux server. For example, in my testing, a Solaris 10 client mounting an FC-5 server fails. When running the attached script, the mtime on the file, bar, should change by about 1 minute, 3 times.
Thanx...
ps #!/bin/sh
rm -f foo bar
set -x
touch foo
cp foo bar
stat --format="%n %y" foo bar
sleep 60
cp foo bar
stat --format="%n %y" foo bar
sleep 60
cp foo bar
stat --format="%n %y" foo bar
sleep 60
rm foo
touch foo
cp foo bar
stat --format="%n %y" foo bar
