There has been a constant forth and back on this topic regarding what
the default should be. 

It used to be open, and then it was requested to be closed:

https://bugzilla.redhat.com/show_bug.cgi?id=864080

The kernel folks committed this:

https://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=82aceae4f0d42f03d9ad7d1e90389e731153898f

For me this settles the story for the time being: as long as that is the
default the kernel guys think is appropriate we really should stick to
it. If you don't like this default, please talk to the kernel folks and
convince them to open this up again, and we'll just inherit that then. I
don't think we should override kernel defaults in this area.

I hope this makes sense!
