Currently there is a circular reference between work queue initialization
and kthread initialization. This prevents the kernel thread
infrastructure from initializing until after work queues have been
initialized.

Make it possible for applications to have the kernel free memory
lazily. This reduces a repeated free/malloc cycle from freeing
pages and allocating them, to just marking them freeable. If the
application wants to reuse them before the kernel needs the memory,
not even a page fault will happen.
sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.

It's very common for file systems to need to zero part or all of a page, the
simplist way is just to use kmap_atomic() and memset(). There's actually a
library function in include/linux/highmem.h that does exactly that, but it's
confusingly named memclear_highpage_flush(), which is descriptive of

it looks ok, but I have several questions:
1. why should we bind this to platform_device, what if the gpio device
is not actually a "platform_device", say, a I2C device, a SPI device or
even a USB device?
2. I still doubt the benefit of using of a structure for a gpio, isn't a gpio
number not

And here's a tested version. Curiouser and curiouser. I think the mapping

Resurrect an old patch that uses atomic operation to update ring buffer
index on AIO event queue. This work allows futher application/libaio
optimization to run fast path io_getevents in user space.
I've also added one more change on top of old implementation that rounds
ring buffer size to
This is difficult.
Summary of problem is:
Filesystem on LVM on md/raid1
Add an md/linear to the md/raid1 and fs dies with 'bio too big'.
Where to begin
The fs level builds bios to send down to the device, and it queries
the device to find out how big the bio can be.
There are two ways

Then either we need to define the first element in the struct as
cacheline aligned or move into section where all

The RAID card in question has reported an "SPD CheckSum Error" (bad
ram?) during system power on so it's looking like this is probably a
hardware or firmware problem and not a driver issue.

Here is a trivial conversion of the v850 arch to the GENERIC_TIME
infrastructure. While the v850 does not currently have better then
jiffies resolution, it does have some #if 0'ed infrastructure that looks
like its being implemented, however I've not seen anything for a few
months.
