Subject: [PATCH] hrtimer: convert net::sched_cbq to the new hrtimer apis

Hi,

as part of a rework of select/poll and hrtimers, I needed to make a slight
API adjustment to networking code; the patch for this is below.

Is it ok to carry this patch as part of the hrtimer tree?
(if not it's going to be .. interesting in terms of sequencing the
introduction of new apis versus this patch versus the rest)

Subject: [PATCH] hrtimer: convert net::sched_cbq to the new hrtimer apis

In order to be able to do range hrtimers we need to use accessor functions
to the "expire" member of the hrtimer struct.
This patch converts sched_cbq to these accessors.
