      Linus Torvalds authored
      Pull clk updates from Stephen Boyd:
       "This contains no changes to the core framework. It is a collection of
        various clk driver updates.
      
        The biggest driver updates in terms of lines of code is the Allwinner
        driver, closely followed by the Qualcomm and Mediatek drivers. All of
        those hit high because we add so many lines of clk data. Coming in
        fourth place is i.MX which also adds a bunch of clk data. This
        accounts for the new driver additions this time around.
      
        Otherwise the patches are lots of little cleanups and fixes for
        various clk drivers that have baked in linux-next for a while. I
        suppose one highlight or theme is that more clk drivers are being
        updated to work as modules, which is interesting to see such critical
        SoC infrastructure work as a loadable module.
      
        New Drivers:
         - Support qcom SM8150/SM8250 video and display clks
         - Support Mediatek MT8167 clks
         - Add clock for CRC block found on vf610 SoCs
         - Add support for the Renesas R-Car V3U (R8A779A0) SoC
         - Add support for the VSP for Resizing clock on Renesas RZ/G1H
         - Support Allwinner A100 SoC clks
      
        Removed Drivers:
         - Remove i.MX21 clock driver, as i.MX21 platform support is being
           dropped
      
        Updates:
         - Change how qcom's display port clks work
         - Small non-critical fixes for TI clk driver
         - Remove various unused variables in clk drivers
         - Allow Rockchip clk driver to be a module
         - Remove most __clk_lookup() calls in Samsung drivers (yay!)
         - Support building i.MX ARMv8 platforms clock driver as module
         - Some kerneldoc fixes here and there
         - A couple of minor i.MX clk data corrections
         - Update audio clock inverter and fdiv2 flag on Amlogic g12
         - Make amlogic clk drivers configurable in Kconfig
         - Fix Renesas VSP clock names to match corrected hardware
           documentation
         - Sigma-delta modulation on Allwinner R40
         - Various fixes for at91 clk driver
         - Use semicolons instead of commas in some places
         - Mark some variables const so they can move to RO memory"

       "The siginificant new ext4 feature this time around is Harshad's new
        fast_commit mode.
      
        In addition, thanks to Mauricio for fixing a race where mmap'ed pages
        that are being changed in parallel with a data=journal transaction
        commit could result in bad checksums in the failure that could cause
        journal replays to fail.
      
        Also notable is Ritesh's buffered write optimization which can result
        in significant improvements on parallel write workloads. (The kernel
        test robot reported a 330.6% improvement on fio.write_iops on a 96

      ext4: fix invalid inode checksum · 13221811
      Luo Meng authored
      During the stability test, there are some errors:
        ext4_lookup:1590: inode #6967: comm fsstress: iget: checksum invalid.
      
      If the inode->i_iblocks too big and doesn't set huge file flag, checksum
      will not be recalculated when update the inode information to it's buffer.
      If other inode marks the buffer dirty, then the inconsistent inode will
      be flushed to disk.
      
      Fix this problem by checking i_blocks in advance.

      Harshad Shirwadkar authored
      This patch adds fast commit recovery path support for Ext4 file
      system. We add several helper functions that are similar in spirit to
      e2fsprogs journal recovery path handlers. Example of such functions
      include - a simple block allocator, idempotent block bitmap update
      function etc. Using these routines and the fast commit log in the fast
      commit area, the recovery path (ext4_fc_replay()) performs fast commit
      log recovery.

      ext4: main fast-commit commit path · aa75f4d3
      Harshad Shirwadkar authored
      This patch adds main fast commit commit path handlers. The overall
      patch can be divided into two inter-related parts:
      
      (A) Metadata updates tracking
      
          This part consists of helper functions to track changes that need
          to be committed during a commit operation. These updates are
          maintained by Ext4 in different in-memory queues. Following are
          the APIs and their short description that are implemented in this
          patch:
      
          - ext4_fc_track_link/unlink/creat() - Track unlink. link and creat
            operations
          - ext4_fc_track_range() - Track changed logical block offsets
            inodes
          - ext4_fc_track_inode() - Track inodes
          - ext4_fc_mark_ineligible() - Mark file system fast commit
            ineligible()
          - ext4_fc_start_update() / ext4_fc_stop_update() /
            ext4_fc_start_ineligible() / ext4_fc_stop_ineligible() These
            functions are useful for co-ordinating inode updates with
            commits.
      
      (B) Main commit Path
      
          This part consists of functions to convert updates tracked in
          in-memory data structures into on-disk commits. Function
          ext4_fc_commit() is the main entry point to commit path.

      Linus Torvalds authored
      Pull i2c updates from Wolfram Sang:
      
       - if a host can be a client, too, the I2C core can now use it to
         emulate SMBus HostNotify support (STM32 and R-Car added this so far)
      
       - also for client mode, a testunit has been added. It can create rare
         situations on the bus, so host controllers can be tested
      
       - a binding has been added to mark the bus as "single-master". This
         allows for better timeout detections
      
       - new driver for Mellanox Bluefield
      
       - massive refactoring of the Tegra driver
      
       - EEPROMs recognized by the at24 driver can now have custom names
      
       - rest is driver updates
