A call to forget_cached_acl() was recently added to the lustre file system, but this is only available when CONFIG_FS_POSIX_ACL is enabled, otherwise the build now fails with: lustre/llite/file.c: In function 'll_get_acl': lustre/llite/file.c:3134:2: error: implicit declaration of function 'forget_cached_acl' [-Werror=implicit-function-declaration] forget_cached_acl(inode, type); This adds one more #ifdef for this call, corresponding to the other 22 such checks for ACL in lustre.

The lloop device was original developed to work around the lack of direct I/O for the default loop back device. Also the lloop device greatly out performed the default loop back device. The lloop hasn't been worked on for some time and now it no longer out performs the loop device and loop now supports direct I/O. Since this is the case we can delete this device. Signed-off-by:

Merge tag 'iio-for-4.8a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First round of IIO new device support, features and cleanups for the 4.8 cycle. New device support * ads1015 - add ads1115 support * bma220 accelerometer - new driver - triggered buffer support. * bmc150 - add bmm150 support. * bmp280 - bme280 support with addition of humidity channel. * max5487 potentiometer - new driver * MMA7660FC accelerometer. - New driver * st-pressure - support for the lps22hb * loop trigger. - This one is *nasty* but we have real applications (parrot drones) where it is useful. The trigger basically spins as hard as it can firing off a new trigger each time all triggered devices come back to say they are done. It doesn't hang a machine even when doing it on a dummy driver. A lot nicer than having this implemented within lots of device drivers anyway. Core stuff * Add support to create IIO devices via configfs (similar to we did for triggers a while back) + docs. * New channel types - IIO_ELECTRICAL_CONDUCTIVITY * Couple of MAINTAINERS patches to list the device tree bindings. * Make trigger ops structure non optional (comment fix). It hasn't been for an awful long time, but that's not what the description said. New features * ak8975 - support adapters that are limited to byte data only by allowing the emulated block read i2c function that was recently introduced. * atlas-ph - support atlas-ec (electrical conductivity sensor) * bmi160 - add available frequency and scale attributes to make the driver more user friendly (and avoid having to read the datasheet to know what will work). * dummy - move creation to configfs interface. It's not real hardware so we are not that worried about the ABI breakage ;) * mma8452 - oversampling ration support * nau7802 - expose available gains to make life easier for userspace. * st-sensors - allow use of emulation for SMBus block reads as all the st parts support it. * ti-ads1015 - list datasheet names to allow their use by inkernel consumers. * Various module alias additions to help auto probing. Drop one redundant one as well. Cleanups * ad7266, ad7476, ad7887, ad7923, ad799x - use direct mode claim function rather than open coding it during sensor read (prevents switching on buffers mid read). * ad7793, ad7791 - use direct mode claim to prevent frequency changes when buffers running. * afe440x - These are ABI breaking but the driver requires custom userspace code to do anything useful anyway and that is still being written and under control of TI. Ultimately we may have other libraries to do pulse oximetry with these devices but we aren't aware of any yet. - kernel-doc format fixes - drop ifdef fun around of_match_ptr - it's not worth the mess to save a tiny amount of space. - drop some unnecessary register initializations. - drop the weird locked gain modes as they gain us nothing (can just set all gains separately). - remove handling of offset attributes seeing as no channels actually have them (oops) - Drop the LED3 input channel as it's an alias for ALED2. - *big one* remove channel names - an experiment that turned out to not make sense - see patch for details. - use regmap fields to clean up code. - tie the tia gain stages to appropriate channels in the ABI as that is what they really effect. Same with the LED currents. - cleanout some unused defines and fix a missnamed one. * atlas-ph - reorganise to allow support of other similar parts. * bmc150 - document supported chips in kconfig help. * jsa1212 - drop an unneeded i2c functionality check for functionality the driver doesn't use. * mxs-lradc - simply touch screen registration code. - remove the touch screen unregister as all devm based now. - disable only those channels that are masked in hardware stop (others are already dealt with elsewhere) * st-sensors - unexport st_sensors_get_buffer_element as nothing outside the st-sensors core driver uses it. - fix handling of failure to start up regulators. * tpl0102 - drop an i2c functionality test for features that aren't needed. * ti-am335x - use variable name rather than type in sizeof for clarity. - use SIMPLE_DEV_PM_OPS helper macro to tidy up a bit. Tools * Add install / uninstall to makefile. Someone cares, so presumably some people will find it useful! * generic_buffer - rename to iio_generic_buffer to line up with other tools. - handle cleanup when receiving signals - Add a --device-num option and a --trigger-num option rather than relying on naming which doesn't work if you have two of the same part.

Tim Sell authored
debugfs info for each visorhba device is now presented by a file named of the following form within the debugfs tree: visorhba/vbus<x>:dev<y>/info where <x> is the vbus number, and <y> is the relative device number. Also, the debugfs presentation function was converted to use the seq_file interface, so that it could access the device context without resorting to a global array. This also simplified the function.

This patch is necessary to enable ANY task mgmt command to complete successfully via visorhba. When issuing a task mgmt command (CMD_SCSITASKMGMT_TYPE) to the IO partition (back-end), forward_taskmgmt_command() includes pointers within the command area that will be used to wake up the issuing process and provide the result when the command completes: cmdrsp->scsitaskmgmt.notify_handle = (u64)¬ifyevent; cmdrsp->scsitaskmgmt.notifyresult_handle = (u64)¬ifyresult; 'notify_handle' is a pointer to a 'wait_queue_head_t' variable, and 'notifyresult' is a pointer to an int. Both of these are just local stack variables in the issuing process. The way it's supposed to happen is that when the IO partition completes the command, in our completion handling we get copies of those pointers back from the IO partition, where we stash the result of the command at '*notifyresult' (which should not be 0xffff, because that is the initial value that the caller is looking to see a change in), and wake up the wait queue at '*notify_handle'. There are several places we do that dance, but prior to this patch, we always do it WRONG, like: cmdrsp->scsitaskmgmt.notifyresult_handle = TASK_MGMT_FAILED; wake_up_all((wait_queue_head_t *)cmdrsp->scsitaskmgmt.notify_handle); The wake_up_all() part is correct (albeit with the help of the sloppy pointer casting, but that's irrelevant to the bug), but the assignment of 'notifyresult_handle' is WRONG, and SHOULD read: *(int *)(cmdrsp->scsitaskmgmt.notifyresult_handle) = TASK_MGMT_FAILED; Without this change, the caller is NEVER going to notice a change in his local value of 'notifyresult' when he does the: if (!wait_event_timeout(notifyevent, notifyresult != 0xffff, msecs_to_jiffies(45000))) and hence will be timing out EVERY taskmgmt command. This patch also eliminates the need for sloppy casting of pointers back-and-forth between u64 values, with the help of idr_alloc() to provide handles for us. It is the generated int handles we pass to the IO partition to denote our completion context, and these are validated and converted back to the required pointers when the task mgmt commands are returned back to us by the IO partition. == Testing == You must enable dynamic debugging in visorhba (build kernel with 'CONFIG_DYNAMIC_DEBUG=y', provide kernel parameter 'visorhba.dyndbg=+p') to see kernel messages involved with visorhba scsi task mgmt commands, which were added in this patch in the form of a few dev_dbg() / pr_debug() messages. In order to inject faults necessary to get visorhba to actully issue scsi task mgmt commands, you will need to compile a kernel with CONFIG_FAIL_IO_TIMEOUT and friends, in the "Kernel hacking" section: * Enable "Fault-injection framework" * Enable "Fault-injection capability for disk IO" * Enable "Fault-injection capability for faking disk interrupts" * Enable "Debugfs entries for fault-injection capabilities" When running a kernel with those options, you can manually inject a fault that will force a scsi task mgmt command to be issued like this: # mount -t debugfs nodev /sys/kernel/debug # cd /sys/kernel/debug/fail_io_timeout # cat interval 1 # cat probability 0 # cat times 1 # echo 100 >probability # cd /sys/block/sda # l | grep fail -rw-r--r-- 1 root root 4096 May 5 10:53 io-timeout-fail -rw-r--r-- 1 root root 4096 May 5 10:54 make-it-fail # echo 1 >io-timeout-fail # echo 1 >make-it-fail To test this patch, after performing the above steps, I did something to force a block device i/o, then shortly afterwards examined the kernel log. There I found evidence that visorhba had successfully issued a task mgmt command, and that it completed successfully: [ 333.352612] FAULT_INJECTION: forcing a failure. name fail_io_timeout, interval 1, probability 100, space 0, times 1 [ 333.352617] CPU: 0 PID: 295 Comm: vhba_incoming Tainted: G C 4.6.0-rc3-ARCH+ #2 [ 333.352619] Hardware name: Dell Inc.
