Brian Behlendorf 7bd04f2d7d Set default zvol elevator to noop
It doesn't make sense for a zvol to use the default system I/O
scheduler because it is a virtual device.  Therefore, we change
the default scheduler to 'noop' for zvols provided that the
elevator_change() function is available.  This interface has
been available since Linux 2.6.36 and appears in the RHEL 6.x
kernels.

We deliberately do not implement the method for older kernels
because it was racy and could result in system crashes.  It's
better to simply manually tune the scheduler for these kernels.
