[SCSI] retry with missing data for INQUIRY

This patch changes scsi_probe_lun() to retry INQUIRY if the device has
not actually sent back any INQUIRY data,

This enables the Thecus N2050 storage device to work better. The
firmware on that device starts up strangely; it sends no data in
response to the initial INQUIRY, and it sends the INQUIRY information
in response to the followup REQUEST SENSE. But after that it works
better, so retrying the INQUIRY is enough to get it going.

     4. I'd prefer not to default initialise the action variable because
        that ensures that every leg of the error handler has an

15 years ago[SCSI] scsi_error: TASK ABORTED status handling improvement
Vladislav Bolkhovitin [Thu, 6 Nov 2008 10:57:52 +0000 (13:57 +0300)]
[SCSI] scsi_error: TASK ABORTED status handling improvement

This patch improves handling of TASK ABORTED status by Linux SCSI
mid-layer. Currently, command returned with this status considered
failed and returned to upper layers. It leads to additional error
recovery load on file systems and block layer, which sometimes can
cause undesired side effects, like I/O errors and file systems
corruptions. See http://lkml.org/lkml/2008/11/1/38, for instance.

From other side, TASK ABORTED status is returned by SCSI target if the
corresponding command was aborted by another initiator and the target
has TAS bit set in the control mode page. So, in the majority of cases
commands with TASK ABORTED status should be simply retried. In other
cases, maybe_retry path will not retry if no retries are allowed.

This patch implement suggestion by James Bottomley from
http://marc.info/?l=linux-scsi&m=121932916906009&w=2.

Due to an ambiguity in the VIOS VFC interface specification,

completion of commands. In order to cancel all outstanding commands to

net: Allow dependancies of FDDI & Tokenring to be modular.

I noticed it isn't possible to build token ring & fddi drivers
without causing LLC, and a bunch of other things to be forced
built-in.  For distro kernels, this means carrying a chunk of
code in the vmlinuz, even if the user doesn't use those protocols.

gro: Fix potential use after free

The initial skb may have been freed after napi_gro_complete in
napi_gro_receive if it was merged into an existing packet.  Thus
we cannot check same_flow (which indicates whether it was merged)
