[PATCH] block: move blk_register_queue() before uevent is send out
From: Kay Sievers <kay.sievers(a)vrfy.org> Subject: block: move blk_register_queue() before uevent is send out Sysfs attributes should be created before the device is announced to userspace. Createing attributes after the event makes it impossible to use them reliably from udev. The issue was found by Karel. ... 30 Jul 2010 05:20

[PATCH] block: move register_disk() from fs/partitions/check.c to genhd.c and unexport it
From: Kay Sievers <kay.sievers(a)vrfy.org> Subject: block: move register_disk() from fs/partitions/check.c to genhd.c and unexport it Disk code belongs into genhd, not in the partition code. Follow-up patches will need to re-shuffle some code, which needs to be in one file, to fix bad sysfs attribute creation timi... 30 Jul 2010 05:20

[PATCH -mm] add DMA_xxBIT_MASK to feature-removal-schedule.txt
DMA_xxBIT_MASK macros were marked as deprecated in June 2009. One more year is long enough, I think.

[PATCH 0/6] [RFC] Large weight differential leads to inefficient load balancing
Hi all, We have observed that a large weight differential between tasks on a runqueue leads to sub-optimal machine utilization and poor load balancing. For example, if you have lots of SCHED_IDLE tasks (sufficient number to keep the machine 100% busy) and a few SCHED_NORMAL soaker tasks, we see that the machine h... 30 Jul 2010 02:07

[PATCH 3/6] sched: add moving average of time spent servicing SCHED_NORMAL tasks
This patch adds a moving average of time spent servicing SCHED_NORMAL tasks. This metric is maintained at rq->norm_avg and is similar to rq->rt_avg. This is metric is used to provide a measure of cpu power available to run SCHED_IDLE tasks. Signed-off-by: Nikhil Rao <ncrao(a)google.com> --- kernel/sched.c |... 30 Jul 2010 02:07

[PATCH 4/6] sched: add sched_idle_balance argument to lb functions
This patch adds an extra sched_idle_balance argument to move_tasks, load_balance_fair and balance_tasks. This argument is required to differentiate between SCHED_NORMAL/SCHED_BATCH load balancing and SCHED_IDLE balancing.
