staging: lustre: osc: Use SOFT_SYNC to urge server commit
This change adds a BRW page flag, OBD_BRW_SOFT_SYNC. This flag is
intended to urge a server to commit a client's unstable pages to
stable storage. A client will add this flag to any BRW requests while
it is in a state where it has "many" unstable pages pinned in its cache.
The server, upon receiving a page with this flag set, *should* begin
an async commit. The idea being that, with the proactive async commit,
the client's pinned unstable pages will transition into a stable state
faster than they would have otherwise. Although, the server side portion
of this agreement is still unimplemented, so the OBD_BRW_SOFT_SYNC flag
will currently fall on deaf ears.
staging: lustre: osc: Track number of "unstable" pages per osc
This change adds simple accounting hooks for "unstable" pages on a per
OSC basis. Now, in addition to the per filesystem tracking, each OSC
will maintain a running total of its unstable pages. These counters are
exported through the proc interface, and can be read using the lctl
command.
For example:
# Read number of unstable pages contained by each OSC
lctl get_param osc.*.unstable_stats
The motivation for this change is in anticipation of implementing a
"soft sync" functionality, urging servers to commit these unstable
pages to stable storage. The per OSC accounting allows a client to
limit the soft sync request to only the OSCs which have outstanding
unstable pages.
staging: lustre: osc: Track and limit "unstable" pages
This change adds a global counter to track the number of "unstable"
pages held by a given client, along with per file system counters. An
"unstable" page is defined as a page which has been sent to the server
as part of a bulk request, but is uncommitted to stable storage.
In addition to simply tracking the unstable pages, they now also count
towards the maximum number of "pinned" pages on the system at any given
time. Thus, a client will now be bound on the number of dirty and
unstable pages it can pin in memory. Previously only dirty pages were
accounted for in this limit.
In addition to tracking the number of unstable pages in Lustre, the
NR_UNSTABLE_NFS memory zone is also incremented and decremented for
easy monitoring using the "NFS_Unstable:" field in /proc/meminfo.
This field is also used internally by the kernel to limit the total
amount of unstable pages on the system.
The motivation for this change is twofold. First, the client must not
allow itself to disconnect from an OST while still holding unstable
pages. Otherwise, these unstable pages can get lost due to an OST
failure, and replay is not possible due to the disconnect via unmount.
Secondly, the client needs a mechanism to prevent it from allocating too
much of its available RAM to unreclaimable pages pinned by the ptlrpc
layer. If this case occurs, out of memory events can trigger as a side
effect, which we need to avoid.
The current number of unstable pages accounted for on a per file system
granularity is exported by the unstable_stats proc file, contained under
each file system's llite namespace. An example of retrieving this
information is below:
Fix 'error handling' issues found by Coverity version 6.6.1:
Unchecked return value (CHECKED_RETURN)
Calling function without checking return value.
Argument cannot be negative (NEGATIVE_RETURNS)

staging: lustre: ldlm: refine LU-2665 patch for POSIX compliance
Follow-on to patch introduced to fix LU-2665 ticket (Gerrit
Change at http://review.whamcloud.com/6415 with Change-Id:
I8faa331712abeadee46eabe111ee1c23a05840d5).
Original patch introduced regressions against POSIX test suite
(fcntl.18/fcntl.35 tests in LSB-VSX POSIX test suite at
http://www.opengroup.org/testing/linux-test/lsb-vsx.html),
so the idea is to only resend F_UNLCKs to have both LU-2665 bug
and POSIX test suite happy.

2nd set of new device support, features and cleanup for IIO in the 4.7 cycle.
Bit of a bumper set for new drivers but plenty of other stuff here as well!
New device support
* ad5592R ADC/DAC
- new driver supporting ad5592r and ad5593r combined ADC/DAC and gpio chips.
* Aosong am2315 relative humidity
- new driver with triggered buffer support in follow up patch.
* bmi160 imu
- new driver
* bmp280
- bmp180 support - note there is support in the misc/bmp085 driver. Intent
is to remove that driver long term.
* invensense mpu6050
- cleanup leading to explicit support of mpu9150 with a good few cleanups
along the way.
* Hope RF hp03 pressure and temperature sensor.
- new driver
* maxim DS1803 potentiometer
- new driver
* maxim max44000 light and proximity sensor
- new driver built in a series of steps to support pretty much everything.
* ROHM BH1780 light sensor
- new driver. There is an existing driver in misc that this is pretty much
intended to replace. The discussion on whether to support the non standard
interface of that driver is some way is continuing.
* st-gyro
- lsm9ds0-gyro. The accel/magn side of this will take a while longer as
extensions to the st library are needed for cases where two types of sensor
share a single i2c address.
* ti-adc081c
- support the adc101c and adc121c
* Vishay VEML6070 UV sensor
- new driver.
New features
* core
- devm_ APIs for channel_get and channel_get_all. The first user of these
is the generic ADC based thermal driver. As it is going through the
thermal tree these will be picked up as a patch to that next cycle as that
is how the author preferred to do it.
- mounting matrix support. This new core support allows devices to provide
to userspace (typically from the device tree) allowing compensation for how
the sensor is mounted on the device. First examples are on UAVs but it
has a more mundane use on typical phone where the chip may be on the front
or the back of the circuit board and soldered at any angle. Includes
support for this ABI in ak8975 (which has an older interface, now
deprecated) and mpu6050.
* tools
- add a -a option to enable all available channels in generic_buffer sample.
Makes it somewhat easier to use.
* adis library and drivers
- support manual self test flag clearing. This has technically been broken
for a very long time - result is an offset on readings as the applied field
is on all the time.
* ak8975
- triggered buffer support
* bmc150
- spi support (including splitting the driver into core and i2c parts)
* bmp280
- oversampling support.
* dht11
- improved logging - useful to debug timing issues on this quirky device.
* st-sensors
- read each channel invidivually as not all support the optimization of
reading in bulk. This is technically a fix, but will need to be backported
if desired.
- support open drain and shared interrupts.
* ti-adc081c
- triggered buffer support.
Cleanups
* inkern
- white space fix.
* ad7606
- use the iio_device_claim_direct_mode call rather than open coding equiv.
* ad799x
- white space fix.
* ad9523
- unsigned -> unsigned int
* apds9660
- brace location tidying up.
- silence an uninitialized variable warning.
* ak8975
- else and brace on same line fix.
* at91_adc
- white space fixes.
* bmc150
- use regmap stored copy of the device pointer rather than having an
additional copy.
* bmg160
- use regmap stored copy of the device pointer rather than having an
additional copy.
* hid-sensors
- white space fixes.
* mcp3422
- white space fix.
* mma7455
- use regmap to retrieve the device struct rather than carrying another copy
in the private data.
* ms_sensors
- white space fix.
* mxs-lradc
- move current bindings out of staging - some will be shortly deprecated but
the reality is that we have device trees out there using them so they will
need to be supported for some time. They accidentally got left behind
when the driver graduated from staging.
- white space cleanup.
- set INPUT_PROP_DIRECT.
- move ts config into a better function.
- move the STMP reset out of the ADC init.
* vf610_adc
- case label indenting fix.
iio: inv_mpu6050: Add explicit support for MPU9150
This device is a package containing a MPU6050-like sensor and an AK8975
magnetometer. The magnetometer component is supported by the existing
ak8975 driver.
This patch also rephrases the Kconfig descriptions.

iio: inv_mpu6050: Check WHO_AM_I register on probe
This can be used to distinguish mpu6500. This is a warning rather than
an error because the differences are mostly irrelevant and it's nice to
avoid breaking users with slightly incorrect ACPI/DT.
