The workqueues "ioc->reset_work_q" and "ioc->fw_event_q" queue a single
work item &ioc->fault_reset_work and &fw_event->work, respectively and
hence don't require ordering. Hence, they have been converted to use
alloc_workqueue().The WQ_MEM_RECLAIM flag has been set to ensure forward progress under
memory pressure since the workqueue belongs to a storage driver which is
being used on a memory reclaim path.Since there are fixed number of work items, explicit concurrency limit
is unnecessary here.Signed-off-by: Bhaktipriya Shridhar

On larger installations it is useful to disable automatic LUN scanning,
and only add the required LUNs via udev rules. This can speed up bootup
dramatically.This patch introduces a new scan module parameter value 'manual', which
works like 'none', but can be overridden by setting the 'rescan' value
from scsi_scan_target to 'SCSI_SCAN_MANUAL'. And it updates all
relevant callers to set the 'rescan' value to 'SCSI_SCAN_MANUAL' if
invoked via the 'scan' option in sysfs.Signed-off-by: Hannes Reinecke

If and when this gets enabled the driver could should split
up IO memory space properly and that is quite a bit of work.
Just remove the uncommented dead MTRR code then.There are a few motivations for this:
a) Take advantage of PAT when available
b) Help bury MTRR code away, MTRR is architecture specific and on
x86 its replaced by PATc) Help with the goal of eventually using _PAGE_CACHE_UC over
_PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit

The I2O layer deals with a technology that to say the least didn't catch on
in the market.The only relevant products are some of the AMI MegaRAID - which supported I2O
and its native mode (The native mode is faster and runs on Linux), an
obscure crypto ethernet card that's now so many years out of date nobody
would use it, the old DPT controllers, which speak their own dialect and
have their own driver - and ermm.. thats about it.We also know the code isn't in good shape as recently a patch was proposed
and queried as buggy, which in turn showed the existing code was broken
already by prior "clean up" and nobody had noticed that either.It's coding style robot code nothing more. Like some forgotten corridor
cleaned relentlessly by a lost Roomba but where no user has trodden in years.Move it to staging and then to /dev/null.
The headers remain as they are shared with dpt_i2o.

Remove the tagged argument from scsi_adjust_queue_depth, and just let it
handle the queue depth. For most drivers those two are fairly separate,
given that most modern drivers don't care about the SCSI "tagged" status
of a command at all, and many old drivers allow queuing of multiple
untagged commands in the driver.Instead we start out with the ->simple_tags flag set before calling
->slave_configure, which is how all drivers actually looking at
->simple_tags except for one worke anyway. The one other case looks
broken, but I've kept the behavior as-is for now.Except for that we only change ->simple_tags from the ->change_queue_type,
and when rejecting a tag message in a single driver, so keeping this
churn out of scsi_adjust_queue_depth is a clear win.Now that the usage of scsi_adjust_queue_depth is more obvious we can
also remove all the trivial instances in ->slave_alloc or ->slave_configure
that just set it to the cmd_per_lun default.Signed-off-by: Christoph Hellwig

Avoid taking the queue_lock to check the per-device queue limit. Instead
we do an atomic_inc_return early on to grab our slot in the queue,
and if necessary decrement it after finishing all checks.Unlike the host and target busy counters this doesn't allow us to avoid the
queue_lock in the request_fn due to the way the interface works, but it'll
allow us to prepare for using the blk-mq code, which doesn't use the
queue_lock at all, and it at least avoids a queue_lock round trip in
scsi_device_unbusy, which is still important given how busy the queue_lock
is.Signed-off-by: Christoph Hellwig

Convert i2o_res_alloc() to use pci_bus_alloc_resource() rather than
pci_find_parent_resource() and allocate_resource(). We don't have a
resource to start with, so pci_find_parent_resource() can't do anything
useful: a bus may have several memory resources available, so there might
be several possible parents. This is more likely on root buses because
host bridges may have any number of apertures.I'm pretty sure this didn't work in the first place because it passed
size == min == max to allocate_resource(). The min and max parameters are
constraints on the *addresses* of the resource, not on its size, so I think
it was impossible for allocate_resource() to succeed.Signed-off-by: Bjorn Helgaas
