I'm not volunteering to look into this, but can you also
provide more information about your configuration? The two
most interesting items would be:

- What filesystem underlies the test export and the scratch
filesystem?

- is READ_PLUS support enabled on your test client? Look
for the CONFIG_NFS_V4_2_READ_PLUS setting in your client's
kernel configuration.
