Andrew, I'd suggest it for 2.6.25.
It's a safer version of the reverted patch in .24-rc8. It was tested
on ext2/ext3/jfs/xfs/reiserfs and won't 100% iowait even without the
other bug fixing patches.

I bisected the kernel to find out why cfs stopped working.
(open with O_TRUNC returning EINVAL when file already exists on an
cfs file system.)
First I tried to debug cfs itself, and after reading Gianlucas thread on

When an AIO write gets a non-retry error after writing some data
(eg. ENOSPC), it should return the amount written already, not the

This fixes vio_find_name() in arch/powerpc/kernel/vio.c, which is
currently broken because it tries to use devices_subsys. That is bad
for two reasons: (1) it's doing (or trying to do) a scan of all
devices when it should only be scanning those on the vio
When trying to load a module with the same name as a built-in one, a

The driver core, and some other parts of the kernel just want to find a
device based on a name for a specific bus. Give them a simple wrapper
to prevent them from having to always roll their own.
This will be used in the PPC patch later in this series.

This problem is due to the kobject rework recently done in this file.
The mce_amd_64.c code uses some wierd forward calls to back out of the
recursive way the code creates kobjects. Because of this, we need to
verify that we have really created a kobject before calling
kobject_uevent().

Here's 5 patches against your current git tree that fix all of the
reported breakages due to the driver core patch merge.
They fix the following issues:
- build breakage with CONFIG_BLOCK=n
- strange traceback messages when loading a module that is already
built into the kernel.
- ppc
This fixes up the driver core build errors when CONFIG_BLOCK=N

I'm sending printing jobs to a network printer (it's actually printing
to the localhost simply creating a file), and running this on
Linux-2.6.24 will cause the printing to slow down to 1 print every 3
seconds after printing 500 times.
No such symptoms on 2.6.23.12, or 2.6.20.21.

Any reason to prefer .text? It is data at this stage after all.
Technically, it's .rodata...

If two seeks overlap, can't you end up with an f_pos value that is
different than what either thread seeked to? or if you have a seek and
a read overlap can't you end up with the read occurring in the midst
of an update of f_pos (which takes more than one instruction on
various architectures),
