Allow __blk_queue_bounce() to handle bios with more than BIO_MAX_PAGES
segments. Doing that, it becomes possible to simplify the block layer
in the kernel.
The issue is that any code that clones the bio and must clone the biovec

Hi,
I'm trying revive an old debate here[1], though with a simpler approach than
was previously tried. This patch series implements a new option to sanitize
freed pages, a (very) small subset of what is done in PaX/grsecurity[3],
inspired by a previous submission [4].
The first patch is fairly

considered in the upper filesystem(over loop) side already, and
they don't need to be dirtied again.

Yes.
do all architectures handle cache line misalign ed dma accesses
correctly?
x86 does. Most other architectures do not have DMA-coherent caches.

The following patch will use dio/aio to submit IO to backing file,
then it isn't good to schedule IO concurrently from work, so
use kthread_work.
I can't really parse this, what's the specific advantage here?

Add reference counting on a kernel module that exports dma-buf and
implements its operations. This prevents the module from being unloaded
while DMABUF file is in use.
The original patch [1] was submitted by Tomasz, but he's since shifted
jobs and a ping didn't elicit any response.

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is

Oh ok.
So the reason why I cared was:
There is a code in our base which relies on jiffies, but since jiffies are not
incrementing, the code waits there and loops forever.
And forward progress is on halt. (on cpu0, since that is the only cpu, which is
alive)
We have changed the code to use

Early console functions are only used during the early boot stage.
This change just saves a small amount of memory footprint.
