If the device is not present, the driver should disable the queues immediately. Prior to this, the driver was relying on the watchdog timer to kill the queues if requests were outstanding to the device, and that just delays removal up to one second. Signed-off-by:

NVMe devices can advertise multiple power states. These states can be either "operational" (the device is fully functional but possibly slow) or "non-operational" (the device is asleep until woken up). Some devices can automatically enter a non-operational state when idle for a specified amount of time and then automatically wake back up when needed. The hardware configuration is a table. For each state, an entry in the table indicates the next deeper non-operational state, if any, to autonomously transition to and the idle time required before transitioning. This patch teaches the driver to program APST so that each successive non-operational state will be entered after an idle time equal to 100% of the total latency (entry plus exit) associated with that state. The maximum acceptable latency is controlled using dev_pm_qos (e.g. power/pm_qos_latency_tolerance_us in sysfs); non-operational states with total latency greater than this value will not be used. As a special case, setting the latency tolerance to 0 will disable APST entirely. On hardware without APST support, the sysfs file will not be exposed. The latency tolerance for newly-probed devices is set by the module parameter nvme_core.default_ps_max_latency_us. In theory, the device can expose "default" APST table, but this doesn't seem to function correctly on my device (Samsung 950), nor does it seem particularly useful. There is also an optional mechanism by which a configuration can be "saved" so it will be automatically loaded on reset. This can be configured from userspace, but it doesn't seem useful to support in the driver. On my laptop, enabling APST seems to save nearly 1W. The hardware tables can be decoded in userspace with nvme-cli. 'nvme id-ctrl /dev/nvmeN' will show the power state table and 'nvme get-feature -f 0x0c -H /dev/nvme0' will show the current APST configuration. This feature is quirked off on a known-buggy Samsung device. Signed-off-by:

The end_device and sas_host devices support BSG ioctls, but the request_queue allocated for them isn't set up to allocate the struct scsi_request payload. This leads to memory corruption in the call to scsi_req_init() in bsg_map_hdr(), since it will memset past the end of the allocated request. Fix it by setting ->cmd_size on the allocated request_queue. Fixes: 82ed4db4 ("block: split scsi_request out of struct request") Signed-off-by:

Jan Kara authored
When a device gets removed, block device inode unhashed so that it is not used anymore (bdget() will not find it anymore). Later when a new device gets created with the same device number, we create new block device inode. However there may be file system device inodes whose i_bdev still points to the original block device inode and thus we get two active block device inodes for the same device. They will share the same gendisk so the only visible differences will be that page caches will not be coherent and BDIs will be different (the old block device inode still points to unregistered BDI). Fix the problem by checking in bd_acquire() whether i_bdev still points to active block device inode and re-lookup the block device if not. That way any open of a block device happening after the old device has been removed will get correct block device inode. Tested-by:

Move bdev_unhash_inode() after invalidate_partition() as invalidate_partition() looks up bdev and it cannot find the right bdev inode after bdev_unhash_inode() is called. Thus invalidate_partition() would not invalidate page cache of the previously used bdev. Also use part_devt() when calling bdev_unhash_inode() instead of manually creating the device number.

Pull block layer updates from Jens Axboe: - blk-mq scheduling framework from me and Omar, with a port of the deadline scheduler for this framework. A port of BFQ from Paolo is in the works, and should be ready for 4.12. - Various fixups and improvements to the above scheduling framework from Omar, Paolo, Bart, me, others. - Cleanup of the exported sysfs blk-mq data into debugfs, from Omar. This allows us to export more information that helps debug hangs or performance issues, without cluttering or abusing the sysfs API. - Fixes for the sbitmap code, the scalable bitmap code that was migrated from blk-mq, from Omar. - Removal of the BLOCK_PC support in struct request, and refactoring of carrying SCSI payloads in the block layer. This cleans up the code nicely, and enables us to kill the SCSI specific parts of struct request, shrinking it down nicely. From Christoph mainly, with help from Hannes. - Support for ranged discard requests and discard merging, also from Christoph. - Support for OPAL in the block layer, and for NVMe as well. Mainly from Scott Bauer, with fixes/updates from various others folks. - Error code fixup for gdrom from Christophe. - cciss pci irq allocation cleanup from Christoph. - Making the cdrom device operations read only, from Kees Cook. - Fixes for duplicate bdi registrations and bdi/queue life time problems from Jan and Dan. - Set of fixes and updates for lightnvm, from Matias and Javier. - A few fixes for nbd from Josef, using idr to name devices and a workqueue deadlock fix on receive. Also marks Josef as the current maintainer of nbd. - Fix from Josef, overwriting queue settings when the number of hardware queues is updated for a blk-mq device. - NVMe fix from Keith, ensuring that we don't repeatedly mark and IO aborted, if we didn't end up aborting it. - SG gap merging fix from Ming Lei for block. - Loop fix also from Ming, fixing a race and crash between setting loop status and IO. - Two block race fixes from Tahsin, fixing request list iteration and fixing a race between device registration and udev device add notifiations. - Double free fix from cgroup writeback, from Tejun. - Another double free fix in blkcg, from Hou Tao. - Partition overflow fix for EFI from Alden Tondettar. * tag 'for-4.11/linus-merge-signed' of git://git.kernel.dk/linux-block: (156 commits) nvme: Check for Security send/recv support before issuing commands. block/sed-opal: allocate struct opal_dev dynamically block/sed-opal: tone down not supported warnings block: don't defer flushes on blk-mq + scheduling blk-mq-sched: ask scheduler for work, if we failed dispatching leftovers blk-mq: don't special case flush inserts for blk-mq-sched blk-mq-sched: don't add flushes to the head of requeue queue blk-mq: have blk_mq_dispatch_rq_list() return if we queued IO or not block: do not allow updates through sysfs until registration completes lightnvm: set default lun range when no luns are specified lightnvm: fix off-by-one error on target initialization Maintainers: Modify SED list from nvme to block Move stack parameters for sed_ioctl to prevent oversized stack with CONFIG_KASAN uapi: sed-opal fix IOW for activate lsp to use correct struct cdrom: Make device operations read-only elevator: fix loading wrong elevator type for blk-mq devices cciss: switch to pci_irq_alloc_vectors block/loop: fix race between I/O and set_status blk-mq-sched: don't hold queue_lock when calling exit_icq block: set make_request_fn manually in blk_mq_update_nr_hw_queues ...

Pull GFS2 updates from Robert Peterson: "We've got eight GFS2 patches for this merge window: - Andy Price submitted a patch to make gfs2_write_full_page a static function. - Dan Carpenter submitted a patch to fix a ERR_PTR thinko. Three patches fix bugs related to deleting very large files, which cause GFS2 to run out of journal space: - The first one prevents GFS2 delete operation from requesting too much journal space. - The second one fixes a problem whereby GFS2 can hang because it wasn't taking journal space demand into its calculations. - The third one wakes up IO waiters when a flush is done to restart processes stuck waiting for journal space to become available. The final three patches are a performance improvement related to spin_lock contention between multiple writers: - The "tr_touched" variable was switched to a flag to be more atomic and eliminate the possibility of some races. - Function meta_lo_add was moved inline with its only caller to make the code more readable and efficient. - Contention on the gfs2_log_lock spinlock was greatly reduced by avoiding the lock altogether in cases where we don't really need it: buffers that already appear in the appropriate metadata list for the journal.

Pull power management updates from Rafael Wysocki: "The majority of changes go into the Operating Performance Points (OPP) framework and cpufreq this time, followed by devfreq and some scattered updates all over. The OPP changes are mostly related to switching over from RCU-based synchronization, that turned out to be overly complicated and problematic, to reference counting using krefs. In the cpufreq land there are core cleanups, documentation updates, a new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI SoCs that require special handling, ARM64 SoCs support for the qoriq driver, intel_pstate updates, powernv driver update and assorted fixes. The devfreq changes are mostly fixes related to the sysfs interface and some Exynos drivers updates. Apart from that, the cpuidle menu governor will support per-CPU PM QoS constraints for the wakeup latency now, some bugs in the wakeup IRQs framework are fixed, the generic power domains framework should handle asynchronous invocations of *noirq suspend/resume callbacks from now on, the analyze_suspend.py script is updated and there is a new tool for intel_pstate diagnostics. Specifics: - Operating Performance Points (OPP) framework fixes, cleanups and switch over from RCU-based synchronization to reference counting using krefs (Viresh Kumar, Wei Yongjun, Dave Gerlach) - cpufreq core cleanups and documentation updates (Viresh Kumar, Rafael Wysocki) - New cpufreq driver for Broadcom BMIPS SoCs (Markus Mayer) - New cpufreq-dt sub-driver for TI SoCs requiring special handling, like in the AM335x, AM437x, DRA7x, and AM57x families, along with new DT bindings for it (Dave Gerlach, Paul Gortmaker) - ARM64 SoCs support for the qoriq cpufreq driver (Tang Yuantian) - intel_pstate driver updates including a new sysfs knob to control the driver's operation mode and fixes related to the no_turbo sysfs knob and the hardware-managed P-states feature support (Rafael Wysocki, Srinivas Pandruvada) - New interface to export ultra-turbo frequencies for the powernv cpufreq driver (Shilpasri Bhat) - Assorted fixes for cpufreq drivers (Arnd Bergmann, Dan Carpenter, Wei Yongjun) - devfreq core fixes, mostly related to the sysfs interface exported by it (Chanwoo Choi, Chris Diamand) - Updates of the exynos-bus and exynos-ppmu devfreq drivers (Chanwoo Choi) - Device PM QoS extension to support CPUs and support for per-CPU wakeup (device resume) latency constraints in the cpuidle menu governor (Alex Shi) - Wakeup IRQs framework fixes (Grygorii Strashko) - Generic power domains framework update including a fix to make it handle asynchronous invocations of *noirq suspend/resume callbacks correctly (Ulf Hansson, Geert Uytterhoeven) - Assorted fixes and cleanups in the core suspend/hibernate code, PM QoS framework and x86 ACPI idle support code (Corentin Labbe, Geert Uytterhoeven, Geliang Tang, John Keeping, Nick Desaulniers) - Update of the analyze_suspend.py script is updated to version 4.5 offering multiple improvements (Todd Brandt) - New tool for intel_pstate diagnostics using the pstate_sample tracepoint (Doug Smythies)" * tag 'pm-4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (85 commits) MAINTAINERS: cpufreq: add bmips-cpufreq.c PM / QoS: Fix memory leak on resume_latency.notifiers PM / Documentation: Spelling s/wrtie/write/ PM / sleep: Fix test_suspend after sleep state rework cpufreq: CPPC: add ACPI_PROCESSOR dependency cpufreq: make ti-cpufreq explicitly non-modular cpufreq: Do not clear real_cpus mask on policy init tools/power/x86: Debug utility for intel_pstate driver AnalyzeSuspend: fix drag and zoom bug in javascript PM / wakeirq: report a wakeup_event on dedicated wekup irq PM / wakeirq: Fix spurious wake-up events for dedicated wakeirqs PM / wakeirq: Enable dedicated wakeirq for suspend cpufreq: dt: Don't use generic platdev driver for ti-cpufreq platforms cpufreq: ti: Add cpufreq driver to determine available OPPs at runtime Documentation: dt: add bindings for ti-cpufreq PM / OPP: Expose _of_get_opp_desc_node as dev_pm_opp API cpufreq: qoriq: Don't look at clock implementation details cpufreq: qoriq: add ARM64 SoCs support PM / Domains: Provide dummy governors if CONFIG_PM_GENERIC_DOMAINS=n cpufreq: brcmstb-avs-cpufreq: remove unnecessary platform_set_drvdata() ...

Pull LED updates from Jacek Anaszewski: "New features and improvements: - add new optional brightness_hw_changed attribute for the LEDs that may have their brightness level changed autonomously (outside of kernel control) by hardware / firmware. The attribute supports userspace notifications through POLLPRI events - add led_brightness_hw_mon tool that demonstrates how to use the aforementioned feature - add LED_ON enum for LEDs that can be only turned on/off, and don't allow setting other brightness levels - allow for adjusting heartbeat trigger blink brightness level Fixes and cleanups: - avoid harmless maybe-uninitialized warning in leds-ktd2692.c - add context to the existing example entries in common LED bindings to make the documentation more clear" * tag 'leds_for_4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds: leds: ledtrig-heartbeat: Make top brightness adjustable tools/leds: Add led_hw_brightness_mon program leds: class: Add new optional brightness_hw_changed attribute leds: ktd2692: avoid harmless maybe-uninitialized warning leds: add LED_ON brightness as boolean value DT: leds: Improve examples by adding some context
