[PATCH] drm/qxl: replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not

[PATCH][next] drm/nouveau/nvkm: Replace zero-length array with flexible-array member
Zero-length arrays are deprecated[1] and we are moving towards
adopting C99 flexible-array members instead. So, replace zero-length
array declaration in struct nvfw_hs_load_header_v2 with flex-array
member.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [2].

[PATCH 48/82] drm/nouveau/mmu: Refactor intentional wrap-around test
In an effort to separate intentional arithmetic wrap-around from
unexpected wrap-around, we need to refactor places that depend on this
kind of math. One of the most common code patterns of this is:
VAR + value < VAR
Notably, this is considered "undefined behavior" for signed and pointer
types, which the kernel works around by using the -fno-strict-overflow
option in the build[1]

[RFC] Zeroing Caller Saved Regs
[This feature addresses https://bugs.llvm.org/show_bug.cgi?id=37880
and https://github.com/KSPP/linux/issues/84.]
Clang has been ramping up its support of the Linux kernel. We recently
added "asm goto with outputs", a long requested feature. We want to
continue building our relationship with the Linux community.

As suggested by Kees[1], replace the old-style 0-element array members
of multiple structs in ebtables.h with modern C99 flexible array.

[PATCH] virtio_console: free unused buffers with virtio port
The commit a7a69ec0d8e4 ("virtio_console: free buffers after reset")
deffered detaching of unused buffer to virtio device unplug time.
This causes unplug/replug of single port in virtio device with an
error "Error allocating inbufs\n". As we don't free the unused buffers
attached with the port. Re-plug the same port tries to allocate new
buffers in virtqueue

[PATCH] virtio_console: initialize vtermno value for ports
For regular serial ports we do not initialize value of vtermno
variable. A garbage value is assigned for non console ports.
The value can be observed as a random integer with [1].
[1] vim /sys/kernel/debug/virtio-ports/vport*p*
This patch initialize the value of vtermno for console serial
ports to '1' and regular serial ports are initiaized to '0'.

LVM issue
Hi We use AoE disks for some of our systems. Currently, a 15.65Tb filesystem we have is full, I then extended the LVM by a further 4Tb but resize4fs could not handle a filesystem over 16Tb (CentOS 5.5). I then reduced the lvm by the same amount, and attempted to create a new LV, but get this error message in the process
lvcreate -v -ndata2 -L2T -t aoe
Test mode: Metadata will NOT be updated.
