| Tim Chen | Volanomark slows by 80% under CFS
Ingo,
Volanomark slows by 80% with CFS scheduler on 2.6.23-rc1.
Benchmark was run on a 2 socket Core2 machine.
The change in scheduler treatment of sched_yield
could play a part in changing Volanomark behavior.
In CFS, sched_yield is implemented
by dequeueing and requeueing a process . The time a process
has spent running probably reduced the the cpu time due it
by only a bit. The process could get re-queued pretty close
to head of the queue, and may get scheduled again pretty
quickly if...

| Cliff Wickman | ATA scsi driver misbehavior under kdump capture kernel
I've run into a problem with the ATA SCSI disk driver when running in a
kdump dump-capture kernel.
I'm running on 2-processor x86_64 box. It has 2 scsi disks, /dev/sda and
/dev/sdb
My kernel is 2.6.22, and built to be a dump capturing kernel loaded by kexec.
When I boot this kernel by itself, it finds both sda and sdb.
But when it is loaded by kexec and booted on a panic it only finds sda.
Any ideas from those familiar with the ATA driver?

Currently the modinfo looks like:
description: Support for Cisco/Aironet 802.11 wireless ethernet cards. Direct support for ISA/PCI/MPI cards and support for PCMCIA when used with airo_cs.
Arguably, it should be cut at the end of the first sentence.
This at least makes it somewhat more legible.

| Alan Stern | Lockdep violation in the serial driver
I want to make some changes to the Power Management core, and one of
the side effects will be to make it illegal for a driver to acquire a
mutex within its suspend() or resume() method if that mutex was locked
while the device was registered.
Unfortunately the serial core does exactly that. In

state->mutex while calling tty_register_device(), and the same mutex is

| Jesper Juhl | [PATCH][sas] Fix potential NULL pointer dereference bug in s...
Hello,
In sas_smp_get_phy_events() we never test if the call to
alloc_smp_req(RPEL_REQ_SIZE) succeeds or fails. That means we run
the risk of dereferencing a NULL pointer if it does fail. Far
better to test if we got NULL back and in that case return -ENOMEM
just as we already do for the other memory allocation in that
function.
This patch reworks the memory allocation a bit to deal with it
(compile tested only).

| James Bottomley | Re: [PATCH][sas] Fix potential NULL pointer dereference bug ...
Just for the sake of being the same as all the rest of the code, the
sequence should be
req = alloc_smp_req(xxx_REQ_SIZE);
if (!req)
return -ENOMEM;
resp = alloc_smp_resp(xxx_RESP_SIZE);
if (!resp) {
kfree(req);
return -ENOMEM;
}
(allocate request then response).
It looks like disc_resp could use a little love too (it's using the req
alloc routines).

| Al Boldi | swap-prefetch: A smart way to make good use of idle resourc...
IMHO, what everybody agrees on, is that swap-prefetch has a positive effect
in some cases, and nobody can prove an adverse effect (excluding power
consumption). The reason for this positive effect is also crystal clear:
It prefetches from swap on idle into free memory, ie: it doesn't force
anybody out, and they are the first to be dropped without further swap-out,
which sounds really smart.
Conclusion: Either prove swap-prefetch is broken, or get this merged quick.
Thanks!

the fact that there is free memory is ... strange. IN principle, Linux
keeps almost no memory free (except some emergency buffers) so that
things you swap in prematurely will BY DEFINITION go at the expense of
other things that could be there....
also, they take up seek time (5 to 10 msec), so if you were to read
something else at the time you get additional latency.
so the conclusion that it only can be better (if you don't care about
power) is imo premature.
Sure it still can be worth it,...

It's not strange, the use case here is if something memory hungry process
is shut down it leaves behind a lot of free memory. Having things swapped
If there's other disk activity swap prefetch shouldn't do much, so this isn't
There are a whole lot of other requirements too than that it isn't broken (of
which most are fulfilled, but anyway). One reason could be that there's a
better solution out there for the problem swap prefetch tries to solve. That
said, as swap prefetch is here now for a whil...
