[PATCH 0/2] vfs: fix delegated timestamp updates

[Jeff Layton]

We had been seeing some failures in the git regression testsuite when
run on NFS with delegated timestamps enabled. The first patch adds a
tracepoint that was helpful for tracking down the problem. The second
patch _mostly_ fixes the actual issue. With this, the git regression
testsuite is passing a lot more often for me, even when run in the
"stress" configuration under kdevops.

That said, I'm still seeing an occasional failure that I think may be a
problem on the client. I'll send email about that separately.
