      "message": "sched, delay accounting: fix incorrect delay time when constantly waiting on runqueue\n\nThis patch corrects the incorrect value of per process run-queue wait\ntime reported by delay statistics. The anomaly was due to the following\nreason. When a process leaves the CPU and immediately starts waiting for\nCPU on the runqueue (which means it remains in the TASK_RUNNABLE state),\nthe time of re-entry into the run-queue is never recorded. Due to this,\nthe waiting time on the runqueue from this point of re-entry upto the\nnext time it hits the CPU is not accounted for. This is solved by\nrecording the time of re-entry of a process leaving the CPU in the\nsched_info_depart() function IF the process will go back to waiting on\nthe run-queue. This IF condition is verified by checking whether the\nprocess is still in the TASK_RUNNABLE state.\n\nThe patch was tested on 2.6.26-rc6 using two simple CPU hog programs.\nThe values noted prior to the fix did not account for the time spent on\nthe runqueue waiting. After the fix, the correct values were reported\nback to user space.\n\nSigned-off-by: Bharath Ravi \u003cbharathravi1@gmail.com\u003e\nSigned-off-by: Madhava K R  \u003cmadhavakr@gmail.com\u003e\nCc: dhaval@linux.vnet.ibm.com\nCc: vatsa@in.ibm.com\nCc: balbir@in.ibm.com\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "sched: reduce schedstat variable overhead a bit\n\nschedstat is useful in investigating CPU scheduler behavior.  Ideally,\nI think it is beneficial to have it on all the time.  However, the\ncost of turning it on in production system is quite high, largely due\nto number of events it collects and also due to its large memory\nfootprint.\n\nMost of the fields probably don\u0027t need to be full 64-bit on 64-bit\narch.  Rolling over 4 billion events will most like take a long time\nand user space tool can be made to accommodate that.  I\u0027m proposing\nkernel to cut back most of variable width on 64-bit system.  (note,\nthe following patch doesn\u0027t affect 32-bit system).\n\nSigned-off-by: Ken Chen \u003ckenchen@google.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
