Comment (by anarcat):

 >  I don't know enough about XFS to know if filesystem attributes can be
 trusted.

 I would be very surprised if they can't, unless you're doing something
 funky with those. That said, filesystems, in general, can hardly be
 trusted :p

 >  The change looks good if we decide we want to go this route. The JVM
 should use the Intel SHA extensions on recent processors, I don't think
 that we're going to see a huge increase in CPU load.

 Okay.

 What do you think about the discrepancy between the estimated writes
 onionoo self-reports and what Prometheus collects?
