PATCH: softlockup: Fix hung_task_check_count sysctl
I'm seeing spikes of up to 0.5ms in khungtaskd on a large machine. To reduce this source of jitter I tried setting hung_task_check_count to 0: # echo 0 > /proc/sys/kernel/hung_task_check_count which didn't have the intended response. Change to a post increment of max_count, so a value of 0 means check 0 tasks... 30 Nov 2009 15:50

[PATCH-RFC] cfq: Disable low_latency by default for 2.6.32
(cc'ing the people from the page allocator failure thread as this might be relevant to some of their problems) I know this is very last minute but I believe we should consider disabling the "low_latency" tunable for block devices by default for 2.6.32. There was evidence that low_latency was a problem last week ... 26 Nov 2009 07:33
