Subject: mainline kernel fails fstests generic/130 over nfsv4.2

Hi,

It's pretty reproducible for me.

Could anyone look into it? Thanks!

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.

It was xfs.

Test pass with this config enabled. Thanks very much for your time!
