Given that we are closing on 3.9 release, and that one/more of these patches fix a
real issue for us - can you please consider my earlier patch to fix
timer_pending() only for 3.9 [http://www.spinics.net/lists/kernel/msg1508224.html]
This will be a localized / low risk change for this late in cycle.
For 3.10 - assuming preempt_* change is blessed, we can revert this one and add
that fuller/better fix.
What do you think ?
Thx,
-Vineet
