Hello,
this patch set removes use of i_devices from block and character device
code and thus we can remove the list head from struct inode thus saving two
pointers in it.
Since v1 I have split the patches and properly handled character devices (I
broke them last time as Christoph pointed
Now that character device can be freed only after all inodes referencing
it through i_cdev are gone, we can remove all the tracking of inodes
pointing to a character device.

Currently i_cdev reference to a character device isn't accounted in the
reference count of the character device. This then requires us to track
all references through a list of all inodes referencing a character
device which is somewhat clumsy and requires list_head in each inode in
the system.
Block devices use i_devices inode field to track all inodes that
reference a particular block device (through i_bdev field) so that this
reference can be removed when block device inode is being evicted from
memory. However we get a reference to the block device (in fact an inode
holding the block

This series demonstrates cpu frequency scaling via a simple policy
driven by the scheduler. Specifically the policy evaluates cpu frequency
when cpu utilization is updated from enqueue_task_fair and
dequeue_task_fair. The policy itself uses a simple up/down threshold
scheme using the same 80%/20%
Building on top of the scale invariant capacity patches and earlier
patches in this series that prepare CFS for scaling cpu frequency, this
patch implements a simple, naive ondemand-like cpu frequency scaling
policy that is driven by enqueue_task_fair and dequeue_tassk_fair. This
new policy is
It seems useful~!
I'd like to do some test with it~

capacity_of is useful for cpu frequency scaling policies. Share it via
sched.h so that selectable cpu frequency scaling policies can make use
of it.

This patch introduces the ENERGY_AWARE sched feature, which is
implemented using jump labels when SCHED_DEBUG is defined. It is
statically set false when SCHED_DEBUG is not defined. Hence this doesn't
allow energy awareness to be enabled without SCHED_DEBUG. This

No worries, I've already applied the patch (with a modified commit

Currently, arch_trigger_all_cpu_backtrace() is defined in only x86 and sparc
which has nmi interrupt.
But in case of softlockup not a hardlockup, it could be possible to dump
backtrace of all cpus. and this could be helpful for debugging.
for example, if system has 2 cpus.
