Otherwise after one round the writeback index will become beyond the file size and ->writepages() turns into an empty operation. Also, a safety guard is added to limit the wait time for grant to 10 minutes(take recovery into consideration) at maximum in the osc_enter_cache() function. Otherwise, EDQUOT will be returned to the applications to start sync write. Signed-off-by:

Since st_blocks = NULL is returned for released files, FIEMAP should at least return a minimal mapping to make users aware that file contains data but it is not immediately available. This will make coreutils and tools such tar happy and have them presume file is sparse. Also, add a new test_228 in sanity-hsm to verify it works for "[cp,tar] --sparse" commands. Also fix a LBUG ("lov_fiemap()) ASSERTION( fm_local ) failed") likely to occur when no-object/ENOMEM conditions and also now when released. Signed-off-by: -

If we specify multiple --mgsnode for a MDT, when we start MDS upon it while MGS is no the other node, the MGC import connection will always select the local nid (which is one of the candidate mgsnode) since it think its the closest connection. This patch treats further --mgsnode nids as failover nids, so that multiple import connections are added for the MGC import. Signed-off-by:

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.

Merge tag 'iio-for-4.7b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing Jonathan writes: 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.

The hw_info array was indexed by enum inv_devices chip_type despite the fact that the enumeration had more members than the array and was ordered differently. The patch cleans this up and adds explicit chip_types to i2c/spi/acpi IDs. It also adds some stricter checks inside the driver core. This happened to work so far because the differences between the supported models are very minor. Signed-off-by:

This patch exposes ALSTIM as illuminance_integration_time and ALSPGA as illuminance_scale. Changing ALSTIM also changes the number of bits available in the data register. This is handled inside raw value reading because: * It's very easy to shift a few bits * It allows SCALE and INT_TIME to be completely independent controls * Buffer support requires constant scan_type.realbits per-channel Signed-off-by:
