Since bsg.h has recently been added to the list of kernel
headers that should be exported to the user space, this
attachment makes bsg.h more user space "friendly".
Specifically autotools dislike headers that don't compile
freestanding and bsg.h's use of __u32 types (and friends)
are not standard C (C90 or C99). The inclusion of
linux/types.h fixes that.

If the iscsi eh fires when the current task is a nop, then
the task->sc pointer is null. fail_all_commands could
then try to do task->sc->device and oops. We actually do
not need to access the curr task in this path, because
if it is a cmd task the fail_command call will handle
this and if it is mgmt task then the flush of the mgmt

The qdepth setting was useful when we needed libiscsi to verify

passed in zero then we need to set some default.

Memory freeing in iscsi_pool_free() looks wrong to me. Either q->pool
can be NULL and this should be tested before dereferencing it, or it
can't be NULL and it shouldn't be tested at all. As far as I can see,
the only case where q->pool is NULL is on early error in
iscsi_pool_init(). One possible way to fix the bug is thus to not
call iscsi_pool_free() in this case (nothing needs to be freed anyway)
and then we can get rid of the q->pool check.

dma_map_sg could return a value different to 'nents' argument of

(e.g. for_each_sg).

Changing the mac address when a macvlan device is up will leave the
device on the wrong hash chain making it impossible to receive
packets.
There is no checking of the mac address set on the macvlan. Allowing
a misconfiguration to grab packets from the the underlying device or
another macvlan.
To resolve these problems I update the hash table of macvlans when the
mac address of a macvlan changes, and when updating the hash table
I verify that the new mac address is usable.
The result is well defined and predictable if not perfect handling of
mac vlan mac addresses.
To keep the code clear I have created a set of hash table maintenance
in macvlan so I am not open coding the hash function and the logic
needed to update the hash table all over the place.

When LLD supports direct data placement (ddp) for large receive of an scsi
i/o coming into fc_fcp, we call into libfc_function_template's ddp_setup()
to prepare for a ddp of large receive for this read I/O. When I/O is complete,
we call the corresponding ddp_done() to get the length of data ddped as well
as to let LLD do clean up.
fc_fcp_ddp_setup()/fc_fcp_ddp_done() are added to setup and complete a ddped
read I/O described by the given fc_fcp_pkt. They would call into corresponding
ddp_setup/ddp_done implemented by the fcoe layer. Eventually, fcoe layer calls
into LLD's ddp_setup/ddp_done provided through net_device

Samsung DB-P70 somehow botched the first ICH9 SATA port. The board
doesn't expose the first port but somehow SStatus reports link online
while failing SRST protocol leading to repeated probe failures and
thus long boot delay.
Because the BIOS doesn't carry any identifying DMI information, the
port can't be blacklisted safely. Fortunately, the controller does
have subsystem vendor and ID set. It's unclear whether the subsystem
IDs are used only for the board but it can be safely worked around by
disabling SIDPR access and just using SRST works around the problem.
Even when the workaround is triggered on an unaffected board the only
side effect will be missing SCR access.

libata keeps a shadow copy of the ATA CTL register (which is write only),
and only writes to the hardware when the required value doesn't match
the shadow. However this copy wasn't being maintained when performing
reset functions. This could cause problems for the first operation after
a reset when the correct value might not be written to the CTL register.
This problem was observed when hotplugging a drive: the identify command
was being issued with interrupts enabled, when they should have been
disabled.
