From 30cfdcfc5f180fc21a3dad6ae3b7b2a9ee112186 Mon Sep 17 00:00:00 2001 From: Dmitry Adamushko Date: Mon, 15 Oct 2007 17:00:07 +0200 Subject: sched: do not keep current in the tree and get rid of sched_entity::fair_key Get rid of 'sched_entity::fair_key'. As a side effect, 'current' is not kept withing the tree for SCHED_NORMAL/BATCH tasks anymore. This simplifies some parts of code (e.g. entity_tick() and yield_task_fair()) and also somewhat optimizes them (e.g. a single update_curr() now vs. dequeue/enqueue() before in entity_tick()).
