We recently added some glock statistics to GFS2, so this is
a docs update to explain what they all mean. It is based
upon the checkin comment of the patch in question.

The previous implementation introduced a randomness in the splitting
of the different touches reported by the device. This version is more
robust as we don't rely on hi->input->absbit, but on our own structure.
This also prepares hid-multitouch to better support Win8 devices.

We setup identity MMU mappings across the entire 4GB of space, which
are permissionless because the domain is set to manager.
This unfortunately allows ARMv6 and later CPUs to speculatively
prefetch from the entire address space, which can cause undesirable
side effects if those regions contain devices.
As we setup the mappings with read/write permission, we can switch
the domain to client mode, and then use the XN bit for ARMv6 and
above to control speculative prefetch to non-RAM areas.

Dial back the aggressiveness of the controller lockup detection thread.
Currently it will declare the controller to be locked up if it goes
for 10 seconds with no interrupts and no change in the heartbeat
register. Dial back this to 30 seconds with no heartbeat change, and
also snoop the ioctl path and if a firmware flash command is detected,
dial it back further to 4 minutes until the firmware flash command
completes. The reason for this is that during the firmware flash
operation, the controller apparently doesn't update the heartbeat
register as frequently as it is supposed to, and we can get a false
positive.

Use spinlocks with finer granularity in the submission and

Smart Arrays can support multiple reply queues onto which command

When aborting a command, the tag is supposed to be
specified as 64-bit little endian. However, some smart
arrays expect the tag of the command to be aborted to be
specified in a strange byte order. How to tell which sort
of Smart Array firmware we're dealing with is not obvious.
However, because of the way we construct our tags, the values
of any outstanding tag when specified with the "strange" byte
order will not collide with the value specified in the correct
order. That means we can safely attempt the abort both ways.

Default behavior for any CHECK CONDITION excepting a few special cases is to
print out certain parts of the sense buffer and the CDB. Default behavior
should be to print nothing and let the upper layers or applications decide what
to do about these. The same information is already available by setting the
appropriate bits of the scsi_logging_level kernel parameter or via
/proc/sys/dev/scsi/logging_level.

There was code to skip "disabled" devices which was intended to
skip devices disabled in the BIOS, but it really just checks to
see if the device can write to host memory, which this is disabled
by pci_disable_device on driver unload, so this check has the effect
of preventing subsequent load of the driver. And devices disabled in
the BIOS don't show up at all anyway, so this check never made any
sense to begin with, and should be removed.

As Jenx Axboe explained to me: "In earlier times (2.6.18 and pre, iirc), Linux
disabled IO and mem bars on pci_disable_device(). Now in newer kernel it does
not. And in the newer kernels you run into problems if you DON'T disable the
device on exit, since when it later loads the device is already in the enabled
state - and pci_enable_device() then does nothing. This typically screws
MSI/MSI-X." This is what the big scary comment that says pci_disable_device
does "something nasty" to smart arrays was evidently referring to.
If pci_disable_device is not called on driver rmmod, subsequently insmod'ing
the driver may in result in some cases fail to be able to receive interrupts,
esp. if other drivers are loaded between unloading and loading hpsa.

This is a followup to a patch provided by Jack Wang on September 21 2011.
After increasing the CAN_QUEUE to 510 in pm8001 we discovered some performance
degredation from time to time. We needed to increase the MPI queue to
compensate and ensure we never hit that limit. We also needed to double
the margin to support event and administrivial commands that take from
the pool resulting in an occasional largely unproductive command completion
with soft error to the caller when the command pool is overloaded temporarily.

UTP Transfer request list base registers UTRLBA and UTRLBAU
must be assigned, lower-32 and upper-32 bits of UTRLD list
physical base addresses respectively.
Currently UTRLBAU is being assigned lower-32 bits of UTRLD
physical base address. This will cause an issue with
controllers that can support 64-bit addressing.
This patch correctly assigns upper-32 bits of UTRLD physical
base address to UTRLBAU.

Remove lport from net device and then do synchronize net device to flush
inflight rx frames for the lport before doing fcoe_percpu_clean.
In case of master lport, remove all rx packet handlers completely and
then only do fcoe_percpu_clean. This required splitting fcoe_interface_cleanup
to do remove part separately and for that added func fcoe_interface_remove
and then call it from fcoe_if_destory before doing fcoe_percpu_clean.
However if fcoe_interface_remove() is already called then
don't call again from fcoe_interface_cleanup() to preserve its
existing flows.
This patch along with Neil's other patch to avoid soft irq context
on ingress will avoid passing up frames on disabled lport as
discussed in this mail thread:-

When a rport is added back or the role is changed the fc class
will queue a scan and then call scsi_target_unblock. The problem
with this is if the devices are in the SDEV_OFFLINE state and
the scan is run before the scsi_target_unblock, then the scan
will see LUN0 as offline and the scan will fail. This patch moves
the unblock call to before the scan, so we know the device state
will be set correctly when the scan is run.

There is a memory leak in the st driver when sending large enough reads or
writes using st's direct I/O path. As part of mapping the application's
memory, a buffer to hold page pointers is allocated and the count of mapped
pages is stored in field do_dio. A non-zero do_dio marks that direct I/O is
in use.
But do_dio is only 1 byte in size. Mapping 256 4k pages overflows
do_dio and causes it to be set to 0, like direct I/O option was not
used. When the I/O completes, the buffer to hold the page pointers is
not freed, and the page counts of the mapped pages are not reduced.
Every I/O of this size then leaks memory.
The size of do_dio needs to be increased to prevent it wrapping around.
