      clk: imx7d: do not set the parent of IMX7D_ENET_AXI_ROOT_SRC · 1fd92dba

      Booting the kernel on a imx7s-warp leads to several warnings like these:

      This fix is along the same lines as 5e33ebff ("clk: imx7d: do not
      set parent of ethernet time/ref clocks") and the explanation from that
      commit is:
      
      "The reason for the warning is that setting the parent enables the ENET
       PLL since we are using CLK_OPS_PARENT_ENABLE. Enabling the ENET PLL can
       cause clk_pllv3_wait_lock to sleep. See also:
       commit fc8726a2 ("clk: core: support clocks which requires parents
       enable (part 2)")."
      
      imx7s-warp does not even use the FEC interface, so we should not really
      configure the parent of IMX7D_ENET_AXI_ROOT_SRC in the common MX7 clock
      driver code.
      
      The dts file should use the assigned-clocks/assigned-clock-parents method,
      so simply remove the configuration of IMX7D_ENET_AXI_ROOT_SRC parent.

      clk: migrate ref counts when orphans are reunited · 904e6ead
      Michael Turquette authored
      It's always nice to see families reunited, and this is equally true when
      talking about parent clocks and their children. However, if the orphan
      clk had a positive prepare_count or enable_count, then we would not
      migrate those counts up the parent chain correctly.
      
      This has manifested with the recent critical clocks feature, which often
      enables clocks very early, before their parents have been registered.
      
      Fixed by replacing the call to clk_core_reparent with calls to
      __clk_set_parent_{before,after}.

      clk: renesas: r8a7795: Fix SD clocks · e0cb1b84
      Yoshihiro Shimoda authored
      According to the datasheet, SDn clocks are from the SDSRC clock. And
      the SDSRC has a 1/2 divider. So, we should have ".sdsrc" as an internal
      core clock. Otherwise, since the sdhi driver will calculate clock for
      a sd card using the wrong parent clock rate, and then performance will
      be not good.

      block: rename bio bi_rw to bi_opf · 1eff9d32
      Jens Axboe authored
      Since commit 63a4cc24, bio->bi_rw contains flags in the lower
      portion and the op code in the higher portions. This means that
      old code that relies on manually setting bi_rw is most likely
      going to be broken. Instead of letting that brokeness linger,
      rename the member, to force old and out-of-tree code to break
      at compile time instead of at runtime.
      
      No intended functional changes in this commit.

      Jens Axboe authored
      Commit abf54548 changed it from an 'rw' flags type to the
      newer ops based interface, but now we're effectively leaking
      some bdev internals to the rest of the kernel. Since we only
      care about whether it's a read or a write at that level, just
      pass in a bool 'is_write' parameter instead.
      
      Then we can also move op_is_write() and friends back under
      CONFIG_BLOCK protection.

      In most cases, EPERM is returned on immutable inode, and there're only a
      few places returning EACCES. I noticed this when running LTP on
      overlayfs, setxattr03 failed due to unexpected EACCES on immutable
      inode.

      Merge tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
      
      Pull more xfs updates from Dave Chinner:
       "This is the second part of the XFS updates for this merge cycle, and
        contains the new reverse block mapping feature for XFS.
      
        Reverse mapping allows us to track the owner of a specific block on
        disk precisely.  It is implemented as a set of btrees (one per
        allocation group) that track the owners of allocated extents.
        Effectively it is a "used space tree" that is updated when we allocate
        or free extents.  i.e. it is coherent with the free space btrees we
        already maintain and never overlaps with them.
      
        This reverse mapping infrastructure is the building block of several
        upcoming features - reflink, copy-on-write data, dedupe, online
        metadata and data scrubbing, highly accurate bad sector/data loss
        reporting to users, and significantly improved reconstruction of
        damaged and corrupted filesystems.  There's a lot of new stuff coming
        along in the next couple of cycles,a nd it all builds in the rmap
        infrastructure.
      
        As such, it's a huge chunk of new code with new on-disk format
        features and internal infrastructure.  It warns at mount time as an
        experimental feature and that it may eat data (as we do with all new
        on-disk features until they stabilise).  We have not released
        userspace suport for it yet - userspace support currently requires
        download from Darrick's xfsprogs repo and build from source, so the
        access to this feature is really developer/tester only at this point.
        Initial userspace support will be released at the same time kernel
        with this code in it is released.
      
        The new rmap enabled code regresses 3 xfstests - all are ENOSPC
        related corner cases, one of which Darrick posted a fix for a few
        hours ago.  The other two are fixed by infrastructure that is part of
        the upcoming reflink patchset.  This new ENOSPC infrastructure
        requires a on-disk format tweak required to keep mount times in
        check - we need to keep an on-disk count of allocated rmapbt blocks so
        we don't have to scan the entire btrees at mount time to count them.
      
        This is currently being tested and will be part of the fixes sent in
        the next week or two so users will not be exposed to this change"
