      ====================
      act_mirred: Ingress actions support
      
      This patch series implements action mirred 'ingress' actions
      TCA_INGRESS_REDIR and TCA_INGRESS_MIRROR.
      
      This allows attaching filters whose target is to hand matching skbs into
      the rx processing of a specified device.
      
      v4:
        in 4/4, check ret code of netif_receive_skb, as suggested by Cong Wang
      v3:
        in 4/4, addressed non coherency due to reading m->tcfm_eaction multiple
        times, as spotted by Eric Dumazet
      v2:
        in 1/4, declare tcfm_mac_header_xmit as bool instead of int

      Shmulik Ladkani 提交于
      Up until now, 'action mirred' supported only egress actions (either
      TCA_EGRESS_REDIR or TCA_EGRESS_MIRROR).
      
      This patch implements the corresponding ingress actions
      TCA_INGRESS_REDIR and TCA_INGRESS_MIRROR.

      net/sched: act_mirred: Rename tcfm_ok_push to tcfm_mac_header_xmit and make it a bool · 16577923
      Shmulik Ladkani 提交于
      'tcfm_ok_push' specifies whether a mac_len sized push is needed upon
      egress to the target device (if action is performed at ingress).
      
      Rename it to 'tcfm_mac_header_xmit' as this is actually an attribute of
      the target device (and use a bool instead of int).
      
      This allows to decouple the attribute from the action to be taken.

      Pull XFS support for shared data extents from Dave Chinner:
       "This is the second part of the XFS updates for this merge cycle.  This
        pullreq contains the new shared data extents feature for XFS.
      
        Given the complexity and size of this change I am expecting - like the
        addition of reverse mapping last cycle - that there will be some
        follow-up bug fixes and cleanups around the -rc3 stage for issues that
        I'm sure will show up once the code hits a wider userbase.
      
        What it is:
      
        At the most basic level we are simply adding shared data extents to
        XFS - i.e. a single extent on disk can now have multiple owners. To do
        this we have to add new on-disk features to both track the shared
        extents and the number of times they've been shared. This is done by
        the new "refcount" btree that sits in every allocation group. When we
        share or unshare an extent, this tree gets updated.
      
        Along with this new tree, the reverse mapping tree needs to be updated
        to track each owner or a shared extent. This also needs to be updated
        ever share/unshare operation. These interactions at extent allocation
        and freeing time have complex ordering and recovery constraints, so
        there's a significant amount of new intent-based transaction code to
        ensure that operations are performed atomically from both the runtime
        and integrity/crash recovery perspectives.
      
        We also need to break sharing when writes hit a shared extent - this
        is where the new copy-on-write implementation comes in. We allocate
        new storage and copy the original data along with the overwrite data
        into the new location. We only do this for data as we don't share
        metadata at all - each inode has it's own metadata that tracks the
        shared data extents, the extents undergoing CoW and it's own private
        extents.
      
        Of course, being XFS, nothing is simple - we use delayed allocation
        for CoW similar to how we use it for normal writes. ENOSPC is a
        significant issue here - we build on the reservation code added in
        4.8-rc1 with the reverse mapping feature to ensure we don't get
        spurious ENOSPC issues part way through a CoW operation. These
        mechanisms also help minimise fragmentation due to repeated CoW
        operations. To further reduce fragmentation overhead, we've also
        introduced a CoW extent size hint, which indicates how large a region
        we should allocate when we execute a CoW operation.
      
        With all this functionality in place, we can hook up .copy_file_range,
        .clone_file_range and .dedupe_file_range and we gain all the
        capabilities of reflink and other vfs provided functionality that
        enable manipulation to shared extents. We also added a fallocate mode
        that explicitly unshares a range of a file, which we implemented as an
        explicit CoW of all the shared extents in a file.
      
        As such, it's a huge chunk of new functionality 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 the kernel
        with this code in it is released.
      
        The new code causes 5-6 new failures with xfstests - these aren't
        serious functional failures but things the output of tests changing
        slightly due to perturbations in layouts, space usage, etc. OTOH,
        we've added 150+ new tests to xfstests that specifically exercise this
        new functionality so it's got far better test coverage than any
        functionality we've previously added to XFS.
      
        Darrick has done a pretty amazing job getting us to this stage, and
        special mention also needs to go to Christoph (review, testing,
        improvements and bug fixes) and Brian (caught several intricate bugs
        during review) for the effort they've also put in.
      
        Summary:
      
         - unshare range (FALLOC_FL_UNSHARE) support for fallocate
      
         - copy-on-write extent size hints (FS_XFLAG_COWEXTSIZE) for fsxattr
           interface
      
         - shared extent support for XFS

       "Here are some more changes I'd like to have in v4.9.  There's one
        small Tegra bug fix in the PHY poweroff path, which is only used in
        failure paths.
      
        The rest is all strictly cleanup that should make host bridge drivers
        more readable, but shouldn't actually change any behavior.
      
        Summary:
      
         - use local struct device pointers in many host bridge drivers for
           clarity
      
         - remove unused platform data
      
         - use generic DesignWare accessors
      
         - misc cleanups: remove redundant structure entries and re-order
           structure members to put comon generic fields first etc"

      Dan Carpenter 提交于
      This is supposed to loop 1000 times and then give up.  The problem is
      it's a post-op and after the loop we test if "loop" is zero when really
      it would be -1.  Fix this by making it a pre-op.

      net: phy: Trigger state machine on state change and not polling. · 3c293f4e
      Andrew Lunn 提交于
      The phy_start() is used to indicate the PHY is now ready to do its
      work. The state is changed, normally to PHY_UP which means that both
      the MAC and the PHY are ready.
      
      If the phy driver is using polling, when the next poll happens, the
      state machine notices the PHY is now in PHY_UP, and kicks off
      auto-negotiation, if needed.
      
      If however, the PHY is using interrupts, there is no polling. The phy
      is stuck in PHY_UP until the next interrupt comes along. And there is
      no reason for the PHY to interrupt.
      
      Have phy_start() schedule the state machine to run, which both speeds
      up the polling use case, and makes the interrupt use case actually
      work.
      
      This problems exists whenever there is a state change which will not
      cause an interrupt. Trigger the state machine in these cases,
      e.g. phy_error().
