  "message": "[PATCH] sched: improve efficiency of sched_fork()\n\nProblem:\n  sched_fork() has always called scheduler_tick() in some (unlikely)\n  circumstances in order to update the current task in light of those\n  circumstances.  It has always been the case that the work done by\n  scheduler_tick() was more than was required to handle the problem in\n  hand but no harm was done except for the waste of a few CPU cycles.\n\n  However, the splitting of scheduler_tick() into two procedures in\n  2.6.20-rc1 enables the wasted cycles to be saved as the new procedure\n  task_running_tick() does all the work that is required to rectify the\n  problem being handled.\n\nSolution:\n  Replace the call to scheduler_tick() in sched_fork() with a call to\n  task_running_tick().\n\nSigned-off-by: Peter Williams \u003cpwil3058@bigpond.com.au\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
