Pull inode->i_version rework from Jeff Layton: "This pile of patches is a rework of the inode->i_version field. We have traditionally incremented that field on every inode data or metadata change. Typically this increment needs to be logged on disk even when nothing else has changed, which is rather expensive. It turns out though that none of the consumers of that field actually require this behavior. The only real requirement for all of them is that it be different iff the inode has changed since the last time the field was checked. Given that, we can optimize away most of the i_version increments and avoid dirtying inode metadata when the only change is to the i_version and no one is querying it. Queries of the i_version field are rather rare, so we can help write performance under many common workloads. This patch series converts existing accesses of the i_version field to a new API, and then converts all of the in-kernel filesystems to use it. The last patch in the series then converts the backend implementation to a scheme that optimizes away a large portion of the metadata updates when no one is looking at it. In my own testing this series significantly helps performance with small I/O sizes. I also got this email for Christmas this year from the kernel test robot (a 244% r/w bandwidth improvement with XFS over DAX, with 4k writes): https://lkml.org/lkml/2017/12/25/8 A few of the earlier patches in this pile are also flowing to you via other trees (mm, integrity, and nfsd trees in particular)". * tag 'iversion-v4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux: (22 commits) fs: handle inode->i_version more efficiently btrfs: only dirty the inode in btrfs_update_time if something was changed xfs: avoid setting XFS_ILOG_CORE if i_version doesn't need incrementing fs: only set S_VERSION when updating times if necessary IMA: switch IMA over to new i_version API xfs: convert to new i_version API ufs: use new i_version API ocfs2: convert to new i_version API nfsd: convert to new i_version API nfs: convert to new i_version API ext4: convert to new i_version API ext2: convert to new i_version API exofs: switch to new i_version API btrfs: convert to new i_version API afs: convert to new i_version API affs: convert to new i_version API fat: convert to new i_version API fs: don't take the i_lock in inode_inc_iversion fs: new API for handling inode->i_version ntfs: remove i_version handling ...

Pull MMC updates from Ulf Hansson: "There are two major achievements for MMC in this release, which deserves to be specially highlighted. First, we have converted the MMC block device from using the legacy blk interface into using the modern blkmq interface. Not only do we get all the nice effects from using blkmq, but it also means that new fresh nice code replaces old rusty code. Great news to everybody that cares about MMC/SD! It should also be noted that converting to blkmq has not been trivial, mostly because of that we have been carrying too much of MMC specific optimizations for the I/O request path, rather than striving to move these to the generic blk layer. Hopefully we won't be doing that mistake, ever again. Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro), who both have been working on this for quite some time! Second, on top of the blkmq deployment, we have enabled full support the eMMC command queuing feature, introduced in the eMMC v.5.1 spec. This also includes an implementation of a host driver library, supporting the corresponding CQHCI HW. Ideally, those controllers that supports CQHCI should only need some minor adaptations to make this play. So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan driver used on Rockchip RK3399, have enabled support for eMMC command queueing. Worth to highlight is also that, implementing the eMMC command queuing support has been a collaborative effort, as several people from Codeaurora, Rockchip, Intel and Linaro have been involved. However, the work has been driven by Adrian Hunter (Intel). In some shadow of the above, here are the rest of the highlights: MMC core: - Don't remove non-removable cards during system suspend - Add a slot-gpio helper to check capability of GPIO WP detection MMC host: - sdhci: Cleanups and improvements of some wakeup related code - sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy - sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT - sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400 - sdhci_f_sdh30: Add ACPI support - sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume - sdhci-of-esdhc: A few minor fixes - mmci: Add support for new STM32 variant - renesas_sdhi: enable R-Car D3 (r8a77995) support - tmio/renesas_sdhi: Re-structuring, cleanups and modernizations" * tag 'mmc-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: (96 commits) mmc: mmci: fix error return code in mmci_probe() mmc: davinci: suppress error message on EPROBE_DEFER mmc: davinci: dont' use module_platform_driver_probe() mmc: tmio: hide unused tmio_mmc_clk_disable/tmio_mmc_clk_enable functions mmc: mmci: Add STM32 variant mmc: mmci: Add support for setting pad type via pinctrl mmc: mmci: Don't pretend all variants to have OPENDRAIN bit mmc: mmci: Don't pretend all variants to have MCI_STARBITERR flag mmc: mmci: Don't pretend all variants to have MMCIMASK1 register mmc: tmio: refactor .get_ro hook mmc: slot-gpio: add a helper to check capability of GPIO WP detection mmc: tmio: remove dma_ops from tmio_mmc_host_probe() argument mmc: tmio: move {tmio_}mmc_of_parse() to tmio_mmc_host_alloc() mmc: tmio: move clk_enable/disable out of tmio_mmc_host_probe() mmc: tmio: ioremap memory resource in tmio_mmc_host_alloc() mmc: sh_mmcif: remove redundant initialization of 'opc' mmc: sdhci: Rework sdhci_enable_irq_wakeups() mmc: sdhci: Handle failure of enable_irq_wake() mmc: sdhci: Stop exporting sdhci_enable_irq_wakeups() mmc: sdhci-pci: Use device wakeup capability to determine MMC_PM_WAKE_SDIO_IRQ capability ...

Pull power management updates from Rafael Wysocki: "This includes some infrastructure changes in the PM core, mostly related to integration between runtime PM and system-wide suspend and hibernation, plus some driver changes depending on them and fixes for issues in that area which have become quite apparent recently. Also included are changes making more x86-based systems use the Low Power Sleep S0 _DSM interface by default, which turned out to be necessary to handle power button wakeups from suspend-to-idle on Surface Pro3. On the cpufreq front we have fixes and cleanups in the core, some new hardware support, driver updates and the removal of some unused code from the CPU cooling thermal driver. Apart from this, the Operating Performance Points (OPP) framework is prepared to be used with power domains in the future and there is a usual bunch of assorted fixes and cleanups. Specifics: - Define a PM driver flag allowing drivers to request that their devices be left in suspend after system-wide transitions to the working state if possible and add support for it to the PCI bus type and the ACPI PM domain (Rafael Wysocki). - Make the PM core carry out optimizations for devices with driver PM flags set in some cases and make a few drivers set those flags (Rafael Wysocki). - Fix and clean up wrapper routines allowing runtime PM device callbacks to be re-used for system-wide PM, change the generic power domains (genpd) framework to stop using those routines incorrectly and fix up a driver depending on that behavior of genpd (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven). - Fix and clean up the PM core's device wakeup framework and re-factor system-wide PM core code related to device wakeup (Rafael Wysocki, Ulf Hansson, Brian Norris). - Make more x86-based systems use the Low Power Sleep S0 _DSM interface by default (to fix power button wakeup from suspend-to-idle on Surface Pro3) and add a kernel command line switch to tell it to ignore the system sleep blacklist in the ACPI core (Rafael Wysocki). - Fix a race condition related to cpufreq governor module removal and clean up the governor management code in the cpufreq core (Rafael Wysocki). - Drop the unused generic code related to the handling of the static power energy usage model in the CPU cooling thermal driver along with the corresponding documentation (Viresh Kumar). - Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh Cheng). - Add a new operating point to the imx6ul and imx6q cpufreq drivers and switch the latter to using clk_bulk_get() (Anson Huang, Dong Aisheng). - Add support for multiple regulators to the TI cpufreq driver along with a new DT binding related to that and clean up that driver somewhat (Dave Gerlach). - Fix a powernv cpufreq driver regression leading to incorrect CPU frequency reporting, fix that driver to deal with non-continguous P-states correctly and clean it up (Gautham Shenoy, Shilpasri Bhat). - Add support for frequency scaling on Armada 37xx SoCs through the generic DT cpufreq driver (Gregory CLEMENT). - Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT). - Fix a transition delay setting regression in the longhaul cpufreq driver (Viresh Kumar). - Add Skylake X (server) support to the intel_pstate cpufreq driver and clean up that driver somewhat (Srinivas Pandruvada). - Clean up the cpufreq statistics collection code (Viresh Kumar). - Drop cluster terminology and dependency on physical_package_id from the PSCI driver and drop dependency on arm_big_little from the SCPI cpufreq driver (Sudeep Holla). - Add support for system-wide suspend and resume to the RAPL power capping driver and drop a redundant semicolon from it (Zhen Han, Luis de Bethencourt). - Make SPI domain validation (in the SCSI SPI transport driver) and system-wide suspend mutually exclusive as they rely on the same underlying mechanism and cannot be carried out at the same time (Bart Van Assche). - Fix the computation of the amount of memory to preallocate in the hibernation core and clean up one function in there (Rainer Fiebig, Kyungsik Lee). - Prepare the Operating Performance Points (OPP) framework for being used with power domains and clean up one function in it (Viresh Kumar, Wei Yongjun). - Clean up the generic sysfs interface for device PM (Andy Shevchenko). - Fix several minor issues in power management frameworks and clean them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven, Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker, Sergey Senozhatsky, gaurav jindal). -

Pull init_task initializer cleanups from David Howells: "It doesn't seem useful to have the init_task in a header file rather than in a normal source file. We could consolidate init_task handling instead and expand out various macros. Here's a series of patches that consolidate init_task handling: (1) Make THREAD_SIZE available to vmlinux.lds for cris, hexagon and openrisc. (2) Alter the INIT_TASK_DATA linker script macro to set init_thread_union and init_stack rather than defining these in C. Insert init_task and init_thread_into into the init_stack area in the linker script as appropriate to the configuration, with different section markers so that they end up correctly ordered. We can then get merge ia64's init_task.c into the main one. We then have a bunch of single-use INIT_*() macros that seem only to be macros because they used to be used per-arch. We can then expand these in place of the user and get rid of a few lines and a lot of backslashes. (3) Expand INIT_TASK() in place. (4) Expand in place various small INIT_*() macros that are defined conditionally. Expand them and surround them by #if[n]def/#endif in the .c file as it takes fewer lines. (5) Expand INIT_SIGNALS() and INIT_SIGHAND() in place. (6) Expand INIT_STRUCT_PID in place.

Since i_version is mostly treated as an opaque value, we can exploit that fact to avoid incrementing it when no one is watching. With that change, we can avoid incrementing the counter on writes, unless someone has queried for it since it was last incremented. If the a/c/mtime don't change, and the i_version hasn't changed, then there's no need to dirty the inode metadata on a write. Convert the i_version counter to an atomic64_t, and use the lowest order bit to hold a flag that will tell whether anyone has queried the value since it was last incremented. When we go to maybe increment it, we fetch the value and check the flag bit. If it's clear then we don't need to do anything if the update isn't being forced. If we do need to update, then we increment the counter by 2, and clear the flag bit, and then use a CAS op to swap it into place. If that works, we return true. If it doesn't then do it again with the value that we fetch from the CAS operation. On the query side, if the flag is already set, then we just shift the value down by 1 bit and return it. Otherwise, we set the flag in our on-stack value and again use cmpxchg to swap it into place if it hasn't changed. If it has, then we use the value from the cmpxchg as the new "old" value and try again. This method allows us to avoid incrementing the counter on writes (and dirtying the metadata) under typical workloads. We only need to increment if it has been queried since it was last changed.

We only really need to update i_version if someone has queried for it since we last incremented it. By doing that, we can avoid having to update the inode if the times haven't changed. If the times have changed, then we go ahead and forcibly increment the counter, under the assumption that we'll be going to the storage anyway, and the increment itself is relatively cheap.

For AFS, it's generally treated as an opaque value, so we use the *_raw variants of the API here. Note that AFS has quite a different definition for this counter. AFS only increments it on changes to the data to the data in regular files and contents of the directories. Inode metadata changes do not result in a version increment. We'll need to reconcile that somehow if we ever want to present this to userspace via statx. Signed-off-by:
