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


Patch Set 1:

I know that we've discussed this, but reviewing the patch (which looks fine by 
the way) I still think the right solution is to change the default scheduler in 
boot parameter.

It easily allows user to:
1. change default scheduler
2. target specific devices and change the scheduler.
Both of the above would not require the user to know about vdsm specific udev 
rules.

In addition, the current rule targets all block devices in the system and if 
users already have code that changes the scheduler for some devices, this would 
override it and they might not even be aware of the change (but suffer from a 
performance hit).
