Change subject: storage: set block schedule elevator using udev
......................................................................


Patch Set 1:

> How about a user-editable blacklist of devices were vdsm-elevator.rules does not apply?

As I wrote in the inline comment... you just copy our rule to a different name with higher number and add the statement of your device, for example:

 ACTION=="add|change", SUBSYSTEM=="block", ENV{DEVTYPE}=="disk", KERNEL='sda',RUN+="vdsm-elevator.sh cfq"

So if we use udev, we do not actually need to re-invent the wheel of rule base processing... it is all there.
