rdac hardware handler assumes that there is one-to-one relation ship
between the host and the controller w.r.t lun. IOW, it does not
support "multiple storage partitions" within a storage.
Example:
HBA1 and HBA2 see lun 0 and 1 in storage A (1)
HBA3 and HBA4 see lun 0 and 1 in storage A (2)
HBA5 and HBA6 see lun 0 and 1 in storage A (3)
luns 0 and 1 in (1), (2) and (3) are totally different.
But, rdac handler treats the lun 0s (and lun 1s) as the same when
sending a mode select to the controller, which is wrong.
This patch makes the rdac hardware handler associate HBA and the
storage w.r.t lun (and not the host itself).

irq_domain_generate_simple() is an easy way to generate an irq translation
domain for simple irq controllers. It assumes a flat 1:1 mapping from
hardware irq number to an offset of the first linux irq number assigned
to the controller
Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
This patch adds irq_domain infrastructure for translating from
hardware irq numbers to linux irqs. This is particularly important
for architectures adding device tree support because the current
implementation (excluding PowerPC and SPARC) cannot handle
translation for more than a single interrupt controller. irq_domain
supports device tree translation for any number of interrupt
controllers.
This patch converts x86, Microblaze, ARM and MIPS to use irq_domain
for device tree irq translation. x86 is untested beyond compiling it,
irq_domain is enabled for MIPS and Microblaze, but the old behaviour is
preserved until the core code is modified to actually register an
irq_domain yet. On ARM it works and is required for much of the new
ARM device tree board support.
PowerPC has /not/ been converted to use this new infrastructure. It
is still missing some features before it can replace the virq
infrastructure already in powerpc (see documentation on
irq_domain_map/unmap for details). Followup patches will add the
missing pieces and migrate PowerPC to use irq_domain.
SPARC has its own method of managing interrupts from the device tree
and is unaffected by this change.

I noticed that you took some time back in late 2009 to 'consolidate' the
split format-strings present in the bonding driver at the time and I've
decided I'm fine to leave them the way they are. The main point of my
patch was to change the output and I would like to get that included.
Here is my updated patch...
Subject: [PATCH net-next-2.6 v2] bonding: reduce noise during init
Many are using sysfs to configure bonding rather than module options, so
there is no need for bonding to throw this warning in normal cases.
Keep the message around when debugging is enabled as it might be useful
for someone desperate enough to enable debugging, but eliminate it
otherwise.

When a bond contains a device where one name is the subset of another
(eth1 and eth10, for example), one cannot properly set the primary
device or the currently active device.
This was reported and based on work by Takuma Umeya. I also verified
the problem and tested that this fix resolves it.
V2: A few did not like the the current code or my changes, so I
refactored bonding_store_primary and bonding_store_active_slave to be a
bit cleaner, dropped the use of strnicmp since we did not really need
the comparison to be case insensitive, and formatted the input string
from sysfs so a comparison to IFNAMSIZ could be used.
I also discovered an error in bonding_store_active_slave that would
modify bond->primary_slave rather than bond->curr_active_slave before
forcing the bonding driver to choose a new active slave.
V3: Actually sending the proper patch....
