I'm belatedly confirming that both patches applied together in <20140607140414.GA26534@infradead.org> and <20140611162238.GA28340@infradead.org> fix the problem I was seeing with NFSv3 client mounts on 3.6.14.x.
I've tried vanilla 3.6.14.6 + both patches and the regression is gone. Remains the issue where on a NFSv3 client.
Phil.
