Yes, thanks very much. But could we use a larger MAX_SLOTS_PER_SESSION
value, to increase the chances this test will make sense for any
server?
Also, this is a "reply", not a "replay", test, so move it a little
later; how about the following?

SRVR: Can server return fore_channel maxreqs correctly
When client set the fore_channel maxreqs larger than server's
NFSD_MAX_SLOTS_PER_SESSION at create_session, the fore_channel
maxreqs at the reply must less than NFSD_MAX_SLOTS_PER_SESSION.
At 2.6.37-rc1, the NFSD_MAX_SLOTS_PER_SESSION is 160.
