  • The current rpmsg_client_sample is a very simple example and
    is not designed to handle multiple instances. Add support for
    multiple instances, so that the same number of pings are sent
    to each instance. The instances can be on one or multiple
    remote processors.

  • There are couple of print_hex_dump traces used in rpmsg code which
    prints the actual byte messages being transferred between host and
    the remote processors. These traces are quiet verbose and affects
    performance, if the appropriate trace level is enabled. These hex
    dumps are needed rather rarely, but are quite useful when debugging
    complex IPC corner cases. So, this patch switches these hex dump
    traces to use the dynamic_hex_dump() API.

    The hex dump traces are also enabled only when CONFIG_DYNAMIC_DEBUG
    is enabled. This switch allows flexibility of controlling these
    traces through dynamic debug, instead of removing them completely.

  • The dma_addr_t types can be printed properly using the %pad

  • These types of error prints are superfluous. The system will

    fix the usage of using a structure instead of the actual

    risk of conflict was reduced. I just rebased the series on top of
    current master, and no new ->bi_rw usage has snuck in"

  • Since commit 63a4cc24867d, 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.

  • Commit abf545484d31 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.

    the misc format file is invoked. However, this doesn't work very well
    in the face of mount namespaces and changeroots, so the F mode opens

  • …nel/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"

    - a stable dm-flakey fix to error read IO during the 'down_interval'

    set/clear QUEUE_FLAG_STOPPED when stopping/starting the dm-mq

    - a DM multipath fix to harden locking of in-core state flags in the
    face of concurrent access while handling path failures under heavy
    IO.

  • Pull block fixes from Jens Axboe:
    "Here's the second round of block updates for this merge window.

    It's a mix of fixes for changes that went in previously in this round,
    and fixes in general. This pull request contains:

    - Fixes for loop from Christoph

    - A bdi vs gendisk lifetime fix from Dan, worth two cookies.

    - A blk-mq timeout fix, when on frozen queues. From Gabriel.

    - Writeback fix from Jan, ensuring that __writeback_single_inode()
    does the right thing.

    - Fix for bio->bi_rw usage in f2fs from me.

    - Error path deadlock fix in blk-mq sysfs registration from me.

    - Floppy O_ACCMODE fix from Jiri.

    - Fix to the new bio op methods from Mike.

    One more followup will be coming here, ensuring that we don't
    propagate the block types outside of block. That, and a rename of
    bio->bi_rw is coming right after -rc1 is cut.

    - Various little fixes"

  • Pull more ACPI updates from Rafael Wysocki:
    "Two more fixes in ACPI drivers, one in the ACPI EC driver
    (stable-candidate) and one in the ACPI button driver.

    Specifics:

    - An ACPI EC driver fix from the 4.3 cycle may cause the ACPICA's
    method reentrancy limit to be exceeded for a _Qxx method due to a
    large number of concurrent EC operations, so prevent that from
    happening by moving the EC handling into a separate workqueue with
    a limit on the number of concurrently executed work items (Lv
    Zheng)

    - Fix the cleanup code in the ACPI button driver that forgets to
    clear two variables on exit which causes an error to occur on the
    next attmpt to load the driver (Benjamin Tissoires)"

  • Pull more power management updates from Rafael Wysocki:
    "A few more fixes and cleanups in the x86-64 low-level hibernation
    code, PM core, cpufreq (Kconfig and intel_pstate), and the operating
    points framework.

    Specifics:

    - Prevent the low-level assembly hibernate code on x86-64 from
    referring to __PAGE_OFFSET directly as a symbol which doesn't work
    when the kernel identity mapping base is randomized, in which case
    __PAGE_OFFSET is a variable (Rafael Wysocki).

    - Avoid selecting CPU_FREQ_STAT by default as the statistics are not
    required for proper cpufreq operation (Borislav Petkov).

    - Add Skylake-X and Broadwell-X IDs to the intel_pstate's list of
    processors where out-of-band (OBB) control of P-states is possible
    and if that is in use, intel_pstate should not attempt to manage
    P-states (Srinivas Pandruvada).

    - Drop some unnecessary checks from the wakeup IRQ handling code in
    the PM core (Markus Elfring).

    - Reduce the number operating performance point (OPP) lookups in one
    of the OPP framework's helper functions (Jisheng Zhang)"

    kfree(). This uses persistent_ram_free() for correct this asymmetry usage.
