Hello,
this patchset adds to the Xen PV block driver support to exploit the multi-
queue block layer API by sharing and using multiple I/O rings in the frontend
and backend. It is the result of my internship for GNOME's Outreach Program
for Women ([1]), in which I was mentored by Konrad Rzeszutek
This commit lets the backend driver advertise the number of available
hardware queues; it also implements gathering from the frontend driver
the number of rings actually available for mapping.

Changes since v1:

Sean Cross (2):
mfd: stmpe: support gpio over irq under device tree
mfd: stmpe: Document DT binding
The stmpe_platform_data has a irq_over_gpio field, which allows the
system to read STMPE events whenever an IRQ occurs on a GPIO pin.
This patch adds the ability to configure this field and to use a GPIO
as an IRQ source for boards configuring the STMPE in device tree.

The statistics structure can serve well for both reader and writer
locks, thus simply rename some fields that mention 'write' and leave
the declaration of lwsa.

Add a mutex_lock torture test. The main difference with the already
existing spinlock tests is that the latency of the critical region
is much larger. We randomly delay for (arbitrarily) either 500 ms or,
otherwise, 25 ms. While this can considerably reduce the amount of
writes compared to non
Regular locks are very different than locks with debugging. For instance
for mutexes, debugging forces to only take the slowpaths. As such, the
locktorture module should take this into account when printing related
information -- specifically when printing user passed parameters, it seems

This set includes general updates throughout the locktorture code.
Particularly support for reader locks are added as well as torturing
mutexes and rwsems. With the recent locking changes, it doesn't hurt
to improve our testing infrastructure, and torturing is definitely
one of them. For specific

Got an bug report from someone using a silicon motion video card in
VGA mode about corruption that they tracked down to 64-bit memory
operations not being supported by the video card, it appears that we
probably shouldn't be using 32-bit copies on VGA memory.

We can easily do so with our new reader lock support. Just an arbitrary
design default: readers have higher (5x) critical region latencies than
writers: 50 ms and 10 ms, respectively.

Most of it is based on what we already have for writers. This allows
readers to be very independent (and thus configurable), enabling
future module parameters to control things such as rw distribution.
Furthermore, readers have their own delaying function, allowing us
to test different rw critical

Hello Masanari.
How did codespell find any uses of reseting?
What version of codespell are you using?
