Pull block fixes from Jens Axboe: "Here's a pull request for 4.11-rc, fixing a set of issues mostly centered around the new scheduling framework. These have been brewing for a while, but split up into what we absolutely need in 4.11, and what we can defer until 4.12. These are well tested, on both single queue and multiqueue setups, and with and without shared tags. They fix several hangs that have happened in testing. This is obviously larger than I would have preferred at this point in time, but I don't think we can shave much off this and still get the desired results. In detail, this pull request contains: - a set of five fixes for NVMe, mostly from Christoph and one from Roland. - a series from Bart, fixing issues with dm-mq and SCSI shared tags and scheduling. Note that one of those patches commit messages may read like an optimization, but it is in fact an important fix for queue restarts in particular. - a series from Omar, most importantly fixing a hang with multiple hardware queues when we fail to get a driver tag. Another important fix in there is for resizing hardware queues, which nbd does when handling multiple sockets for one connection. - fixing an imbalance in putting the ctx for hctx request allocations from Minchan" * 'for-linus' of git://git.kernel.dk/linux-block: blk-mq: Restart a single queue if tag sets are shared dm rq: Avoid that request processing stalls sporadically scsi: Avoid that SCSI queues get stuck blk-mq: Introduce blk_mq_delay_run_hw_queue() blk-mq: remap queues when adding/removing hardware queues blk-mq-sched: fix crash in switch error path blk-mq-sched: set up scheduler tags when bringing up new queues blk-mq-sched: refactor scheduler initialization blk-mq: use the right hctx when getting a driver tag fails nvmet: fix byte swap in nvmet_parse_io_cmd nvmet: fix byte swap in nvmet_execute_write_zeroes nvmet: add missing byte swap in nvmet_get_smart_log nvme: add missing byte swap in nvme_setup_discard nvme: Correct NVMF enum values to match NVMe-oF rev 1.0 block: do not put mq context in blk_mq_alloc_request_hctx

vfs_llseek will check whether the file mode has FMODE_LSEEK, no return failure. But ashmem can be lseek, so add FMODE_LSEEK to ashmem file. Comment From Greg Hackmann: ashmem_llseek() passes the llseek() call through to the backing shmem file. 91360b02ab48 ("ashmem: use vfs_llseek()") changed this from directly calling the file's llseek() op into a VFS layer call. This also adds a check for the FMODE_LSEEK bit, so without that bit ashmem_llseek() now always fails with -ESPIPE.

2017-04-07dm rq: Avoid that request processing stalls sporadicallyBart Van Assche1-0/+1
While running the srp-test software I noticed that request processing stalls sporadically at the beginning of a test, namely when mkfs is run against a dm-mpath device. Every time when that happened the following command was sufficient to resume request processing: echo run >/sys/kernel/debug/block/dm-0/state This patch avoids that such request processing stalls occur.

2017-04-07scsi: Avoid that SCSI queues get stuckBart Van Assche1-3/+3
If a .queue_rq() function returns BLK_MQ_RQ_QUEUE_BUSY then the block driver that implements that function is responsible for rerunning the hardware queue once requests can be queued again successfully. commit 52d7f1b5c2f3 ("blk-mq: Avoid that requeueing starts stopped queues") removed the blk_mq_stop_hw_queue() call from scsi_queue_rq() for the BLK_MQ_RQ_QUEUE_BUSY case. Hence change all calls to functions that are intended to rerun a busy queue such that these examine all hardware queues instead of only stopped queues. Since no other functions than scsi_internal_device_block() and scsi_internal_device_unblock() should ever stop or restart a SCSI queue, change the blk_mq_delay_queue() call into a blk_mq_delay_run_hw_queue() call.

2017-04-07pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()Tony Lindgren5-40/+74
Recent pinctrl changes to allow dynamic allocation of pins exposed one more issue with the pinctrl pins claimed early by the controller itself. This caused a regression for IMX6 pinctrl hogs. Before enabling the pin controller driver we need to wait until it has been properly initialized, then claim the hogs, and only then enable it. To fix the regression, split the code into pinctrl_claim_hogs() and pinctrl_enable(). And then let's require that pinctrl_enable() is always called by the pin controller driver when ready after calling pinctrl_register_and_init().

2017-04-05crypto: caam - fix JR platform device subsequent (re)creationsHoria Geantă2-45/+19
The way Job Ring platform devices are created and released does not allow for multiple create-release cycles. JR0 Platform device creation error JR0 Platform device creation error caam 2100000.caam: no queues configured, terminating caam: probe of 2100000.caam failed with error -12 The reason is that platform devices are created for each job ring: for_each_available_child_of_node(nprop, np) if (of_device_is_compatible(np, "fsl,sec-v4.0-job-ring") || of_device_is_compatible(np, "fsl,sec4.0-job-ring")) { ctrlpriv->jrpdev[ring] = of_platform_device_create(np, NULL, dev); which sets OF_POPULATED on the device node, but then it cleans these up: /* Remove platform devices for JobRs */ for (ring = 0; ring < ctrlpriv->total_jobrs; ring++) { if (ctrlpriv->jrpdev[ring]) of_device_unregister(ctrlpriv->jrpdev[ring]); } which leaves OF_POPULATED set. Use of_platform_populate / of_platform_depopulate instead. This allows for a bit of driver clean-up, jrpdev is no longer needed. Logic changes a bit too: -exit in case of_platform_populate fails, since currently even QI backend depends on JR; true, we no longer support the case when "some" of the JR DT nodes are incorrect -when cleaning up, caam_remove() would also depopulate RTIC in case it would have been populated somewhere else - not the case for now Cc: <stable@vger.kernel.org> Fixes: 313ea293e9c4d ("crypto: caam - Add Platform driver for Job Ring") Reported-by: Russell King <rmk+kernel@armlinux.org.uk> Suggested-by: Rob Herring <robh+dt@kernel.org> Signed-off-by: Horia Geantă <horia.geanta@nxp.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2017-04-04net: ethernet: ti: cpsw: fix race condition during open()Sekhar Nori1-6/+8
TI's cpsw driver handles both OF and non-OF case for phy connect. Unfortunately of_phy_connect() returns NULL on error while phy_connect() returns ERR_PTR(). To handle this, cpsw_slave_open() overrides the return value from phy_connect() to make it NULL or error. This leaves a small window, where cpsw_adjust_link() may be invoked for a slave while slave->phy pointer is temporarily set to -ENODEV (or some other error) before it is finally set to NULL. _cpsw_adjust_link() only handles the NULL case, and an oops results when ERR_PTR() is seen by it. Note that cpsw_adjust_link() checks PHY status for each slave whenever it is invoked. It can so happen that even though phy_connect() for a given slave returns error, _cpsw_adjust_link() is still called for that slave because the link status of another slave changed. Fix this by using a temporary pointer to store return value of {of_}phy_connect() and do a one-time write to slave->phy.

2017-04-03drm/msm: Make sure to detach the MMU during GPU cleanupJordan Crouse2-13/+19
We should be detaching the MMU before destroying the address space. To do this cleanly, the detach has to happen in adreno_gpu_cleanup() because it needs access to structs in adreno_gpu.c. Plus it is better symmetry to have the attach and detach at the same code level. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2017-04-03drm/msm/dsi: Fix bug in dsi_mgr_phy_enableArchit Taneja1-1/+1
A recent commit introduces a bug in dsi_mgr_phy_enable. In the non dual DSI mode, we reset the mdsi (master DSI) PHY. This isn't right since master and slave DSI exist only in dual DSI mode. For the normal mode of operation, we should simply reset the PHY of the DSI device (i.e. msm_dsi) corresponding to the current bridge. Usage of the wrong DSI pointer also resulted in a static checker warning. That too is resolved with this fix.

When system bootup without get sensor property, set sensor property will be fail. If no get_feature operation done before set_feature, the sensor properties will all be the initialized value, which is not the same with sensor real properties. When set sensor property it will write back to sensor the changed perperty data combines with other sensor properties data, it is not right and may be dangerous. In order to get all sensor properties, choose to read one of the sensor properties(no matter read any sensor peroperty, driver will get all the peroperties and return the requested one).

When both accel_3d and gravity sensor are present, iio_device_register() fails with "Duplicate scan index" error. The reason for this is setting of indio_dev->num_channels based on accel_3d channel for both gravity and accel-3d sensor. But number of channels are not same, so for gravity it is pointing to some invalid memory and getting scan_index to compare which may match. To fix this issue, set the indio_dev->num_channels correctly based on the sensor type.
