NFS data corruption listed in 6.1 show stopper

[Rong-En Fan]

Hi,

We are planning to upgrade a NFS server from 5.x to 6.x. However,
we found there is a show stopper of 6.1 about NFS data corruption.
>From the todo page, it says this item is worked in progress. Is this
has been fixed already or not yet?  From the description, it is found
by running fsx (in regression/fsx?), can somebody show how to
reproduce this? We would like to do some tests.

Regards,
