Contrary to previous release, I've kept the core and driver changes in the same branch. We always ended up having dependencies between the two for obvious reasons, so makes more sense to keep them together. That said, I'll probably try and keep more topical branches going forward, especially for cycles that end up being as busy as this one. The major parts of this pull request is: - Improved support for O_DIRECT on block devices, with a small private implementation instead of using the pig that is fs/direct-io.c. From Christoph. - Request completion tracking in a scalable fashion. This is utilized by two components in this pull, the new hybrid polling and the writeback queue throttling code. - Improved support for polling with O_DIRECT, adding a hybrid mode that combines pure polling with an initial sleep. From me. - Support for automatic throttling of writeback queues on the block side. This uses feedback from the device completion latencies to scale the queue on the block side up or down. From me. - Support from SMR drives in the block layer and for SD. From Hannes and Shaun. - Multi-connection support for nbd. From Josef. - Cleanup of request and bio flags, so we have a clear split between which are bio (or rq) private, and which ones are shared. From Christoph. - A set of patches from Bart, that improve how we handle queue stopping and starting in blk-mq. - Support for WRITE_ZEROES from Chaitanya. - Lightnvm updates from Javier/Matias. - Supoort for FC for the nvme-over-fabrics code. From James Smart. - A bunch of fixes from a whole slew of people, too many to name here" * 'for-4.10/block' of git://git.kernel.dk/linux-block: (182 commits) blk-stat: fix a few cases of missing batch flushing blk-flush: run the queue when inserting blk-mq flush elevator: make the rqhash helpers exported blk-mq: abstract out blk_mq_dispatch_rq_list() helper blk-mq: add blk_mq_start_stopped_hw_queue() block: improve handling of the magic discard payload blk-wbt: don't throttle discard or write zeroes nbd: use dev_err_ratelimited in io path nbd: reset the setup task for NBD_CLEAR_SOCK nvme-fabrics: Add FC LLDD loopback driver to test FC-NVME nvme-fabrics: Add target support for FC transport nvme-fabrics: Add host support for FC transport nvme-fabrics: Add FC transport LLDD api definitions nvme-fabrics: Add FC transport FC-NVME definitions nvme-fabrics: Add FC transport error codes to nvme.h Add type 0x28 NVME type code to scsi fc headers nvme-fabrics: patch target code in prep for FC transport support nvme-fabrics: set sqe.command_id in core not transports parser: add u64 number parser nvme-rdma: align to generic ib_event logging helper ...
| * block: split out request-only flags into a new namespaceChristoph Hellwig2016-10-282-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of the REQ_* flags are only used on struct requests, and only of use to the block layer and a few drivers that dig into struct request internals. This patch adds a new req_flags_t rq_flags field to struct request for them, and thus dramatically shrinks the number of common requests. It also removes the unfortunate situation where we have to fit the fields from the same enum into 32 bits for struct bio and 64 bits for struct request.

* | memstick: rtsx_usb_ms: Manage runtime PM when accessing the deviceUlf Hansson2016-10-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Accesses to the rtsx usb device, which is the parent of the rtsx memstick device, must not be done unless it's runtime resumed.

A load average of ~1 on a system that : should be idle is somewhat alarming. : : Change the sleep to be interruptible, but still ignore signals.

* drivers/memstick/host/r592.c: avoid gcc-6 warningArnd Bergmann2016-03-261-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The r592 driver relies on behavior of the DMA mapping API that is normally observed but not guaranteed by the API. Instead it uses a runtime check to fail transfers if the API ever behaves When CONFIG_NEED_SG_DMA_LENGTH is not set, one of the checks turns into a comparison of a variable with itself, which gcc-6.0 now warns about: drivers/memstick/host/r592.c: In function 'r592_transfer_fifo_dma': drivers/memstick/host/r592.c:302:31: error: self-comparison always evaluates to false [-Werror=tautological-compare] (sg_dma_len(&dev->req->sg) < dev->req->sg.length)) { ^ The check itself is not a problem, so this patch just rephrases the condition in a way that gcc does not consider an indication of a mistake. We already know that dev->req->sg.length was initially R592_LFIFO_SIZE, so we can compare it to that constant again.

| | | | | | | | | | | | | | | | | | This patch is used to add support for ms card. The main difference between ms card and mspro card is long data transfer mode. mspro card can use auto mode DMA for long data transfer, but ms can not use this mode, it should use normal mode DMA. The memstick core added support for ms card, but the original driver will make ms card fail at initialization, because it uses auto mode DMA. This patch makes the ms card work properly.

No new drivers this time, but a bunch of fairly big cleanups: - Roger Quadros worked on a OMAP USBHS and TLL platform data consolidation, OMAP5 support and clock management code cleanup. - The first step of a major sync for the ab8500 driver from Lee Jones. In particular, the debugfs and the sysct interfaces got extended and improved. - Peter Ujfalusi sent a nice patchset for cleaning and fixing the twl-core driver, with a much needed module id lookup code improvement. - The regular wm5102 and arizona cleanups and fixes from Mark Brown. - Laxman Dewangan extended the palmas APIs in order to implement the palmas GPIO and rt drivers. - Laxman also added DT support for the tps65090 driver. - The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra and Darren Hart. - Linus Walleij patchset for the ab8500 driver allowed ab8500 and ab9540 based devices to switch to the new abx500 pin-ctrl driver. - The max8925 now has device tree and irqdomain support thanks to Qing Xu. - The recently added rtsx driver got a few cleanups and fixes for a better card detection code path and now also supports the RTS5227 chipset, thanks to Wei Wang and Roger Tseng." * tag 'mfd-3.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (109 commits) mfd: lpc_ich: Use devres API to allocate private data mfd: lpc_ich: Add Device IDs for Intel Wellsburg PCH mfd: lpc_sch: Accomodate partial population of the MFD devices mfd: da9052-i2c: Staticize da9052_i2c_fix() mfd: syscon: Fix sparse warning mfd: twl-core: Fix kernel panic on boot mfd: rtsx: Fix issue that booting OS with SD card inserted mfd: ab8500: Fix compile error mfd: Add missing GENERIC_HARDIRQS dependecies Documentation: Add docs for max8925 dt mfd: max8925: Add dts mfd: max8925: Support dt for backlight mfd: max8925: Fix onkey driver irq base mfd: max8925: Fix mfd device register failure mfd: max8925: Add irqdomain for dt mfd: vexpress: Allow vexpress-sysreg to self-initialise mfd: rtsx: Support RTS5227 mfd: rtsx: Implement driving adjustment to device-dependent callbacks mfd: vexpress: Add pseudo-GPIO based LEDs mfd: ab8500: Rename ab8500 to abx500 for hwmon driver ...
| * mfd: rtsx: Fix issue that booting OS with SD card insertedWei WANG2013-02-141-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Realtek card reader supports both SD and MS card. According to the settings of rtsx MFD driver, SD host will be probed before MS host. If we boot/reboot Linux with SD card inserted, the resetting flow of SD card will succeed, and the following resetting flow of MS is sure to fail. Then MS upper-level driver will ask rtsx driver to turn power off. This request leads to the result that the following SD commands fail and SD card can't be accessed again. In this commit, Realtek's SD and MS host driver will check whether the card that upper driver requesting is the one existing in the slot. If not, Realtek's host driver will refuse the operation to make sure the exlusive accessing at the same time.

| | | | | | | | | | | | module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick.

| | | | | | | | | | | | The EXTRA_CFLAGS assignment in memstick/Makefile was not accomplishing anything because this flag only has effect on sources at the same level as the makefile (i.e., per directory). Since both core/ and host/ rely on MEMSTICK_DEBUG, the subdir-ccflags-y variant seems to be the appropriate choice.
