It is preferred that drivers use platform_get_irq() instead of

When setting up CRC offload set ip_summed to CHECKSUM_PARTIAL
instead of CHECKSUM_UNNECESSARY. This is consistent with the
definition of CHECKSUM_PARTIAL.
The only driver that seems to be advertising NETIF_F_FCOE_CRC is
ixgbe. AFICT the driver does not look at ip_summed for FCOE and
just assumes that CRC is being offloaded.

KASAN found that our additional element processing scripts drop off
the end of the VPD page into unallocated space. The reason is that
not every element has additional information but our traversal
routines think they do, leading to them expecting far more additional
information than is present. Fix this by adding a gate to the
traversal routine so that it only processes elements that are expected
to have additional information (list is in SES-2 section 6.1.13.1:
Additional Element Status diagnostic page overview)

If char is signed and one of these bytes happen to have a value outside
the ascii range, the corresponding output will consist of "ffffff"
followed by the two hex chars that were actually intended. One way to
fix it would be to change the casts to (u8*) aka
(unsigned char*), but it is much simpler (and generates smaller code)
to use the %ph extension which was created for such short hexdumps.

The driver is missing calls to pci_dma_mapping_error() after
performing the DMA mapping, which caused DMA-API warning to
show up in dmesg's output. Though that happens only when
DMA_API_DEBUG option is enabled. This change fixes the issue
and makes pvscsi_map_buffers() function more robust.

This reverts commit 49718f0fb8c9 ("SCSI: Fix NULL pointer dereference in
runtime PM")
The old commit may lead to a issue that blk_{pre|post}_runtime_suspend and
blk_{pre|post}_runtime_resume may not be called in pairs.
Take sr device as example, when sr device goes to runtime suspend,
blk_{pre|post}_runtime_suspend will be called since sr device defined
pm->runtime_suspend. But blk_{pre|post}_runtime_resume will not be called
since sr device doesn't have pm->runtime_resume. so, sr device can not
resume correctly anymore.
More discussion can be found from below link.

Simple enclosure implementations (mostly USB) are allowed to return only
page 8 to every diagnostic query. That really confuses our
implementation because we assume the return is the page we asked for and
end up doing incorrect offsets based on bogus information leading to
accesses outside of allocated ranges. Fix that by checking the page
code of the return and giving an error if it isn't the one we asked for.
This should fix reported bugs with USB storage by simply refusing to
attach to enclosures that behave like this. It's also good defensive
practise now that we're starting to see more USB enclosures.

The non-PCI builds of the O day test project are failing:
On Thu, 2015-12-03 at 05:02 +0800, kbuild test robot wrote:
> warning: (SCSI_MPT2SAS) selects SCSI_MPT3SAS which has unmet direct

The problem is that select and depend don't interact because Kconfig doesn't
have a SAT solver, so depend picks up dependencies and select does onward
selects, but select doesn't pick up dependencies. To fix this, we need to add
the correct dependencies to the MPT2SAS option like this.

Add a function scsi_vpd_lun_id() to return a unique device
identifcation based on the designation descriptors of
VPD page 0x83.
As devices might implement several descriptors the order
of preference is:
- NAA IEE Registered Extended
- EUI-64 based 16-byte
- EUI-64 based 12-byte
- NAA IEEE Registered
- NAA IEEE Extended
A SCSI name string descriptor is preferred to all of them
if the identification is longer than 16 bytes.
The returned unique device identification will be formatted
as a SCSI Name string to avoid clashes between different
designator types.

function, called indirectly by device_del(), waits until asynchronous
probing has finished. Since the block layer queue must only be cleaned
up after probing has finished, device_del() has to be called before

duplication.
To avoid problems for people that only have CONFIG_SCSI_MPT2SAS in their

was previously enabled.
This is a temporary measure and we will deprecate this config option in
