recent NFS problems?

[Jeff Garzik <jgarzik@pobox.com>]

This is a bit weird.  Running 2.6.14-g6037d6bb (libata-dev.git branch 
'upstream') on both client and server.  Its latest Linux 
(7015faa7df829876a0f931cd18aa6d7c24a1b581) plus one libata patch.  All 
NFSv4 kernel options are enabled, on both client and server.

On Host A, I mirror a local directory /garz/nsmail to an NFS directory 
Host_B:/g/g/nsmail via rsync+ssh.  Host A also NFS mounts Host_B:/g 
locally.  mount on Host A says

	host_b:/g on /g type nfs (rw,tcp,intr,posix,addr=10.10.10.1)

Seeing some directory weirdness, where wildcard matches fail 
(NFS-related dcache bugs?) but direct accesses succeed:

[jgarzik@host_a~]$ ssh host_b "ls -d /g/g/nsmail/Trash.sbd/*11*"
/g/g/nsmail/Trash.sbd/Sent.20051105
