Subject: [PATCH] vfs: update
The virtqueue_add_buf function has two limitations:

2) it does not support chained scatterlists: the buffers must be
provided as an array of struct scatterlist;
Because of these limitations, virtio-scsi has to copy each
This patch adds queue steering to virtio-scsi. When a target is sent
multiple requests, we always drive them to the same queue so that FIFO
processing order is kept. However, if a target was idle, we can choose
a queue arbitrarily. In this case the queue is chosen according to the
current VCPU,

OMAP and ST-Ericsson platforms are both using mailbox to communicate
with some coprocessors.
Based on OMAP existing mailbox framework, this series proposes a

Now internal structures can remain hidden to the user and just API
related functions and defines are made available.

Current message type is a u32 to fit HW fifo format.
This should be extended to support any message exchanges
and type of mailbox.
Propose structure owns the original u32 and an optional
pointer on additional data.

Actually moving it from plat-omap, as this framework/driver code is
supposed to be under drivers/ folder. The framework should work with
the current supported OMAP processors (OMAP1+) that have mailbox and
can be used as a method of interprocessor communication.
The mailbox hardware (in OMAP)
Some mailboxes are made up of cross interrupts
and associated shared memory.
Shared memory mapping is fixed and cross interrupt/shared
memory relation make impossible the use of virtio.
Mailbox framework must be enough opened to support
any kind of mailbox.

In order to create a generic mailbox framework, functions
and structures should be renamed in mailbox.

For debug purpose, mailbox must be available when
interrupts are disabled to collect dump information.

Please note that I resigned from my position of i2c subsystem
maintainer, so I will not handle this. If you think this is important,
you'll have to resubmit and Wolfram will decide what he wants to do
about it.
OK, I had the impression that the conclusion was that the danger was
