do a VOP_FSYNC() after vop_stddeallocate() to push writes of 0s
This simple patch fixes the case that the
test program finds. I am not 100% sure why
it does fix this, but the code should always
have done this since having the changes
committed to the server before VOP_DEALLOCATE()
returns is required.
Btw, for a newer NFSv4.2 server that supports a
Deallocate operation, your test program works.
(I hacked my server so that Deallocate was
disabled and was able to reproduce the failure
with your test program.)
Maybe asomers@ can test the patch and see if
it fixes all the NFS cases he observes?
