Hello,
I'm seeing a segfault in nfs_dupreq_finish() with 2.6.dev.22. This is
when using NFSv4.0 clients. The dupreq_entry seems to be malformed
(drc is still NULL)

Not sure how most of the fields in dupreq_entry can be zeros when it
reaches nfs_dupreq_finish() - at least rq_xid, rq_prog etc., should
have been filled.
If this is a known issue, please let me know.
Thanks,
