      qedr: Add RoCE driver framework · 2e0cbc4d
      Ram Amrani authored
      Adds a skeletal implementation of the qed* RoCE driver -
      basically the ability to communicate with the qede driver and
      receive notifications from it regarding various init/exit events.

         - Anna Schumacker contributed a simple NFSv4.2 COPY implementation.
           COPY is already supported on the client side, so a call to
           copy_file_range() on a recent client should now result in a
           server-side copy that doesn't require all the data to make a round
           trip to the client and back.
         - Jeff Layton implemented callbacks to notify clients when contended
           locks become available, which should reduce latency on workloads
           with contended locks"

      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
        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.
