[Xen-devel] [PATCH v2 0/3] xen: RCU: Improve the idle timer handling


take 2 of this series. v1 is here:


In patch 2 and patch 3, I took care of Jan's review comments. That meant, in
patch 2, changing how the boot parameter is parsed and handled, from using a
custom_param() to integer_param(). The rest of the changes were simple and

Patch 1 is the one that changed most. Radically, I would say. :-) In fact, I
think we should leave aside, for now, the debate of whether or not it is
necessary to deal with the 'missed' timer handler invocation, in a generic way,
at the timer's code level. For now, it only cause problems to the --rather
special indeed-- RCU idle timer, and there is an easy way to avoid that,
affecting that specific timer only.

So, I'm going for that now. We can re-open the debate later, when not in almost 
freezed state. :-)

Thanks and Regards,

      xen: RCU: make the period of the idle timer adaptive.
