xfstest test

[Steve French]

I sometimes see xfstest generic/207 fail (e.g. to Azure
http://smb311-linux-testing.southcentralus.cloudapp.azure.com/#/builders/5/builds/281/steps/70/logs/stdio)
but usually passes.

e.g. "write of 4096 bytes @5455872 finished, expected filesize at
least 5459968, but got 5455872"

Does anyone else see that fail? or have a better repro scenario to
narrow it down?

Can you collect some tracing from it?

It works for me, but my Azure I/O is so slow that it tends to overlook the
races.

What patches are applied, btw?
