a394aac885 [SCSI] qla2xxx: Test and clear FCPORT_UPDATE_NEEDED atomically.
When the qla2xxx driver loses access to multiple, remote ports, there is a race
condition which can occur which will keep the request stuck on a scsi request
queue indefinitely.

This bad state occurred do to a race condition with how the FCPORT_UPDATE_NEEDED
bit is set in qla2x00_schedule_rport_del(), and how it is cleared in
qla2x00_do_dpc().  The problem port has its drport pointer set, but it has never
been processed by the driver to inform the fc transport that the port has been
lost.  qla2x00_schedule_rport_del() sets drport, and then sets the
FCPORT_UPDATE_NEEDED bit.  In qla2x00_do_dpc(), the port lists are walked and
any drport pointer is handled and the fc transport informed of the port loss,
then the FCPORT_UPDATE_NEEDED bit is cleared.  This leaves a race where the
dpc thread is processing one port removal, another port removal is marked
with a call to qla2x00_schedule_rport_del(), and the dpc thread clears the
bit for both removals, even though only the first removal was actually
handled.  Until another event occurs to set FCPORT_UPDATE_NEEDED, the later
port removal is never finished and qla2xxx stays in a bad state which causes
requests to become stuck on request queues.

This patch updates the driver to test and clear FCPORT_UPDATE_NEEDED
atomically.  This ensures the port state changes are processed and not lost.

63ea923a97 [SCSI] qla2xxx: Properly set result field of bsg_job reply structure for success and failure.
FC transport on receiving bsg_job submission failure, calls bsg_job->job_done()
and sets the bsg_job->reply->result the returned value. In contrast, when the
success code (0) is returned fc transport doesn't call bsg_job->job_done() and
doesn't populate bsg_job->reply->result.

691e3d3175 [SCSI] sd: update sd to use the new pm callbacks
Update sd driver to use the callbacks defined in dev_pm_ops.

sd_freeze is NULL, the bus level callback has taken care of quiescing
the device so there should be nothing needs to be done here.
Consequently, sd_thaw is not needed here either.

suspend, poweroff and runtime suspend share the same routine sd_suspend,
which will sync flush and then stop the drive, this is the same as before.

resume, restore and runtime resume share the same routine sd_resume,
which will start the drive by putting it into active power state, this
is also the same as before.

80d2fd48cc [SCSI] scsi_pm: use callbacks from dev_pm_ops for scsi devices
Use of pm_message_t is deprecated and device driver is not supposed
to use that. This patch migrates the SCSI bus level pm callbacks
to call device's pm callbacks defined in its driver's dev_pm_ops.

This is achieved by finding out which device pm callback should be used
in bus callback function, and then pass that callback function pointer
as a param to the scsi_bus_{suspend,resume}_common routine, which will
further pass that callback to scsi_dev_type_{suspend,resume} after
proper handling.

The special case for freeze in scsi_bus_suspend_common is not necessary
since there is no high level SCSI driver has implemented freeze, so no
need to runtime resume the device if it is in runtime suspended state
for system freeze, just return like the system suspend/hibernate case.

Since only sd has implemented drv->suspend/drv->resume, and I'll update
sd driver to use the new callbacks in the following patch, there is no
need to fallback to call drv->suspend/drv->resume if dev_pm_ops is NULL.

a01475637c [SCSI] sd: put to stopped power state when runtime suspend
When device is runtime suspended, put it to stopped power state to save
some power.

This will also make the behaviour consistent with what the scsi_pm.c
thinks about sd as the comment says:
sd treats runtime suspend, system suspend and system hibernate identical.
With this patch, it is now identical.
And sd_shutdown will also do nothing when it finds the device has been
runtime suspended, if we do not spin down the disk in runtime suspend
by putting it into stopped power state, the disk will be shut down
incorrectly.
And the the same problem can be solved for runtime power off after
runtime suspended case by this change.

With the current runtime scheme for disk, it will only be runtime
suspended when no process opens the disk, so this shouldn't happen a
lot, which makes it acceptable to spin down the disk when runtime
suspended. If some day a more aggressive runtime scheme is used, like
the 'request based runtime pm for disk' that Alan Stern and Lin Ming
has been working, we can introduce some policy to control this. But for
now, make it simple and correct by spinning down the disk.

beecadea1b [SCSI] mvsas: fix undefined bit shift
The macro bit(n) is defined as ((u32)1 << n), and thus it doesn't work
with n >= 32, such as in mvs_94xx_assign_reg_set():

	if (i >= 32) {
		mvi->sata_reg_set |= bit(i);
		...
	}

The shift ((u32)1 << n) with n >= 32 also leads to undefined behavior.
The result varies depending on the architecture.

This patch changes bit(n) to do a 64-bit shift.  It also simplifies
mv_ffc64() using __ffs64(), since invoking ffz() with ~0 is undefined.

072f19b4be [SCSI] prevent stack buffer overflow in host_reset
store_host_reset() has tried to re-invent the wheel to compare sysfs strings.
Unfortunately it did so poorly and never bothered to check the input from
userspace before overwriting stack with it, so something simple as:

echo "WoopsieWoopsie" >
/sys/devices/pseudo_0/adapter0/host0/scsi_host/host0/host_reset

would result in:

[  316.310101] Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: ffffffff81f5bac7

a77cfcb429 fix off-by-one in argument passed by iterate_fd() to callbacks

aeb1e5d69a ext4: fix possible use after free with metadata csum
Commit fa77dcfafe introduces block bitmap checksum calculation into
ext4_new_inode() in the case that block group was uninitialized.
However we brelse() the bitmap buffer before we attempt to checksum it
so we have no guarantee that the buffer is still there.

Fix this by releasing the buffer after the possible checksum
computation.

We changed the sizeof() statements in 429ccf058b "staging:panel: Fixed

line limit.  Unfortunately, the new sizeof() statements are a smaller

05fcdcede0 staging: comedi: addi_apci_2032: fix interrupt support
This board supports two interrupt sources:

VCC : detects when the external supply voltage drops below 5V
CC  : over temperature diagnostic

Currently the interrupt support is tied into the digital output
subdevice. It's also broken since it does not follow the comedi
API.

Create a new digital input subdevice to handle the interrupts.

the apci_1516 board. Fix the i_APCI2032_StartStopWriteWatchdog and

Rename the CamelCase function i_APCI2032_StartStopWriteWatchdog to

Rename the CamelCase function i_APCI2032_ConfigWatchdog to

the watchdog and set the timeout.

The only data in addi_private used in this driver is:

tsk_Current - used with send_sig to signal userspace when an interrupt
has occurred. Interrupt support in this driver does not follow the
standard comedi API so this functionality is currently broken. This
will be addressed.

b_OutputMemoryStatus - used in the addi-data "common" code to enable
reading of the eeprom. Eeprom support is not needed by this driver
and has been removed.
