I have come on a situation where a file in a directory is not showing up
in any directory listings, yet is still accessible by direct access. It
shows up in listings on the server but not on the client. I did a
capture of the NFS protocol traffic, and the file is showing up in the
readdir call results. If I recreate the directory using the same file
names but empty files, the behavior persists.
I am running vanilla 2.6.37.1 on both client and server, using NFSv4.
The server filesystem is ext4.
Is this a kernel NFS client bug? Is there anything else I can do to
diagnose the source of the problem, or any way to work around it?
Thanks.

There is a known bug in readdir that has been fixed in 2.6.38-rc6, but
hasn't yet hit the 2.6.37 stable series. Please check the patch at
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git&a=commitdiff&h=d1205f87bbb8040c1408bbd9e0a720310b2b0b9b
and see if it fixes your problem.
Cheers

Is this a server or client side issue BTW? I am trying to track
something that could be related to this down.
Thanks!
