[RFC PATCH 1/4] Minimally invasive deadline wrap-around bugfix for the SCHED_DEADLINE cpu heap.

From: Tommaso Cucinotta
Date: Thu May 19 2016 - 12:02:47 EST

Next message: Tommaso Cucinotta: "[RFC PATCH 2/4] SCHED_DEADLINE cpu heap code clarification/refactory: - heapify_up factored out in new dedicated function (avoids repeatition of same code) - call to cpudl_change_key replaced with heapify_up when cpudl_set actually inserts a new node in the heap"
