Go for it.  Thanks for asking though :-)

	Hi Ricardo
	
	Is it OK to dump the bakeathon patches into the 2.6.18.3 git
tree? I think the answer is yes -  Just asking 'cause I know you are
moving code to a new kernel....

		Hi Andy,
		 
		I did not run the locking tests in Austin.  The Solaris
client ran the basic and general tests against our server and ran into
problems in the special tests.  We ran out of time to debug it though.

			Hi
			
			I'm testing my Austin final patch set, which
includes setting the clientid in the LOCK/LOCKT and LOCKU operations to
zero. The tests pass - sometimes! When they fail, it is usually in the
connectathon lock tests, after I've run either the basic or special
tests. The lock tests have (so far) always run successfully when run
first. The lock tests always fail on test #12, the 2nd time through test
series. 
			
			The error is on the client which sends two
compounds on the wire with the same session sequence number and slot
number which causes the server to correctly return NFS4ERR_BADSESSION,
and the client hangs.
			
			Connectathon lock test #12 involves a child and
parent one holds the lock, the other waiting, and is then signaled. So
there is a timing piece to the test. 
			
			Has anybody else seen this behaviour? I don't
think it is due to the LOCK patches, and I don't think anyone else ran
the Connectathon lock tests in Austin - is that right?
			
			-->Andy
