Disabling readahead means faster execution queued commands,
since it doesn't have to linger and do unwanted read-ahead.
So this bug is a feature for random access servers.
Had a quick question, this is the first time I have seen this happen, and
it was not even under during heavy I/O, hardly anything was going on with
the box at the time.
Any idea what could have caused this? I am running a badblocks test right
now, but so far the disk looks OK.

The machine is x86_64 SMP. I also got the oops in the Fedora kernels:
2.6.20-1.2933.fc6 and 2.6.20-1.3017.fc7. The system isn't locked solid but
it seems anything touching the scsi disks hangs. I also twice got this early
in the boot and it stopped booting.
Anything I can do to help just ask.

per-backing_dev-dirty-and-writeback-page-accounting.patch
This series implements BDI independent dirty limits and congestion control.
This should solve several problems we currently have in this area:
- mutual interference starvation (for any number of BDIs),
Its redundant, clear_bdi_congested() already wakes the waiters.

When the threshol is in the order of the per cpu inaccuracies we can
deadlock by not receiveing the updated count, introduce a more expensive
but more accurate stat read function to use on low thresholds.

Hi all
I'm pleased to present this patch which improves linux futexes performance and
scalability, merely avoiding taking mmap_sem rwlock.
Ulrich agreed with the API and said glibc work could start as soon
as he gets a Fedora kernel with it :)
Andrew, could we get this in mm as well ? This
