As discussed in [1], KUnit tests have hitherto not had a particularly
consistent naming scheme. This adds documentation outlining how tests
and test suites should be named, including how those names should be
used in Kconfig entries and filenames.

Hi Hyunchul,
No idea why this driver is using a char device node, statically
allocated, with no dynamic allocation or hook up with devtmpfs, along
with a reserverd major number, for "special" operations, not all of
which ever were implemented.

These have shown significantly improved performance and fairness when
spinlock contention is moderate to high on very large systems.
[ Numbers hopefully forthcoming after more testing, but initial
results look good ]
Thanks to the fast path, single threaded performance is not noticably
hurt.
RFC until we settle on queued spinlocks for 64s and remove the
option to go back to simple locks. If other sub-archs want to keep
simple spinlocks, the code can be nicely simplified.

I suggest to recheck the parameter alignment for such a function call.

This patch series extends the MRP netlink interface to allow the userspace
daemon to get the status of the MRP instances in the kernel.

Add MRP attribute IFLA_BRIDGE_MRP_INFO to allow the userspace to get the

This patch extends the function br_fill_ifinfo to return also the MRP
status for each instance on a bridge. It also adds a new filter
RTEXT_FILTER_MRP to return the MRP status only when this is set, not to
interfer with the vlans. The MRP status is return only on the bridge
interfaces.

PinePhone uses PWM backlight and a XBD599 LCD panel over DSI for
display.
Backlight levels curve was optimized by Martijn Braam using a
lux meter.

Some of the virtio drivers (like virtio_rpmsg_bus.c) use sleeping
functions like mutex_*() in the virtqueue callback. Use
request_threaded_irq() instead of request_irq() in order for
the virtqueue callbacks to be executed in thread context instead
of interrupt context.

Introduce standard driver model in VHOST. This will facilitate using
multiple VHOST drivers (like net, scsi etc.,) over different VHOST
devices using MMIO (like PCIe or NTB), using kernel pointers (like
platform devices) or using userspace pointers.
