The variable ret is being checked for failure however it is not being set

Thanks, now applied.

It is common for services to be stateless around their main event loop.
If a process sets PR_SET_IDLE to PR_IDLE_MODE_KILLME then it
signals to the kernel that epoll_wait() and friends may not complete,
and the kernel may send SIGKILL if resources get tight.

Hi Vishal,
In probe(), it calls imx274_load_default(imx274), which has I2C
register read/write to the IMX274. If it fails, it will exit probe().
So it works as a sensor detection function as you suggested.

I can queue 1 up in the dma-mapping tree, and if I get reviews for
the mips and scsi bits I'd be happy to queue those up as well.
But I think you'd be better off moving patches 3 and 4 to the front
without the dma_get_cache_alignment prototype change so that they can be
merged to stable.

This patch fixes a bug for phy supported feature initialization.
Currently, the value of phydev->supported is initialized by kernel.
So it includes many features that we do not support, such as
SUPPORTED_FIBRE and SUPPORTED_BNC. This patch fixes it.

The total memory size we get in kernel is usually slightly less than 2G with a
2G memory module machine. The main reason is bios/firmware reserve some area
it will not export all memory as usable to Linux.

UEFI boot with ovmf: 0x7ef1

During block exchange in {insert,collapse,move}_range, page-block mapping
is unstable due to mapping moving or recovery, so there should be no
concurrent cache read operation rely on such mapping, nor cache write
operation to mess up block exchange.
So this patch let background GC be aware of that

Commit f9cf3b2880cc ("platform/x86: hp-wmi: Refactor dock and tablet
state fetchers") consolidated the methods for docking and laptop mode
detection, but omitted to apply the correct mask for the laptop mode
(it always uses the constant for docking).

Currently if the autofs kernel module gets an error when
writing to the pipe which links to the daemon, then it
marks the whole moutpoint as catatonic, and it will stop working.
It is possible that the error is transient. This can happen
if the daemon is slow and more than 16 requests queue up.

Some reserved pages, such as those from NVDIMM DAX devices, are
not for MMIO, and can be mapped with cached memory type for better
