Currently NetApp's VID/PID details in the INQUIRY response shows up as
'NETAPP' and 'LUN'. With upcoming scalable SAN ONTAP version on NetApp
controllers, the PID entry alone is being modified to 'LUN C-Mode' (to
distinguish current ONTAP LUNs from scalable ONTAP LUNs).
'LUN' would still suffice for matching 'LUN C-Mode' but best to
explicitly add these new NetApp LUNs to the device list.

submit_stpg() will always return failure so alua_activate() will report
failure via dm-multipath callback function. Even though the stpg fired
successfuly dm-multipath does not know and always fails to change the
valid path.
By returning SCSI_DH_OK we're now skipping alua_activate()'s call to
activate_complete 'fn'. But this is fine because stpg_endio() will call
it via h->callback_fn().

Basic Code Cleanup:

scsiio,
hi_priority, and internal.
(2) The hi_priority and internal request queue struct was made
smaller
by removing the scmd and chain_tracker, thus saving memory
allocation.
(3) For scsiio request, a new structure was created having the same
elements from the former request tracker struct.

* 'BUG_ON' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-for-linus:
Remove MAYBE_BUILD_BUG_ON
BUILD_BUG_ON: make it handle more cases
* git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-for-linus:
module: fix missing semicolons in MODULE macro usage
param: add null statement to compiled-in module params
module: fix linker error for MODULE_VERSION when !MODULE and CONFIG_SYSFS=n
module: show version information for built-in modules in sysfs
BUILD_BUG_ON used to use the optimizer to do code elimination or fail
at link time; it was changed to first the size of a negative array (a
nicer compile time error), then (in
8c87df457c) to a bitfield.
This forced us to change some non-constant cases to MAYBE_BUILD_BUG_ON();
as Jan points out in that commit, it didn't work as intended anyway.
bitfields: needs a literal constant at parse time, and can't be put under
"if (__builtin_constant_p(x))" for example.
negative array: can handle anything, but if the compiler can't tell it's
a constant, silently has no effect.
link time: breaks link if the compiler can't determine the value, but the
linker output is not usually as informative as a compiler error.
If we use the negative-array-size method *and* the link time trick,
we get the ability to use BUILD_BUG_ON() under __builtin_constant_p()
branches, and maximal ability for the compiler to detect errors at
build time.
We also document it thoroughly.

Currently only drivers that are built as modules have their versions
shown in /sys/module/<module_name>/version, but this information might
also be useful for built-in drivers as well. This especially important
for drivers that do not define any parameters - such drivers, if
built-in, are completely invisible from userspace.
This patch changes MODULE_VERSION() macro so that in case when we are
compiling built-in module, version information is stored in a separate
section. Kernel then uses this data to create 'version' sysfs attribute
in the same fashion it creates attributes for module parameters.
