    The :c:type:`foo` only works properly with structs before
    Sphinx 3.x.

    On Sphinx 3.x, structs should now be declared using the
    .. c:struct, and referenced via :c:struct tag.

    As we now have the automarkup.py macro, that automatically
    convert:
    struct foo

    into cross-references, let's get rid of that, solving
    several warnings when building docs with Sphinx 3.x.

  • 3b481d913   block: add zone specific block statuses ... Browse Code »

    A zoned device with limited resources to open or activate zones may
    return an error when the host exceeds those limits. The same command may
    be successful if retried later, but the host needs to wait for specific
    zone states before it should expect a retry to succeed. Have the block
    layer provide an appropriate status for these conditions so applications
    can distinuguish this error for special handling.

    Export max_active_zones according to this new definition for NVMe Zoned
    Namespace devices, ZAC ATA devices (which are treated as SCSI devices by
    the kernel), and ZBC SCSI devices.

    Add the new max_active_zones member to struct request_queue, rather
    than as a queue limit, since this property cannot be split across stacking
    drivers.

    For SCSI devices, even though max active zones is not part of the ZBC/ZAC
    spec, export max_active_zones as 0, signifying "no limit".

    Pull btrfs updates from David Sterba:
    "Highlights:

    - speedup dead root detection during orphan cleanup, eg. when there
    are many deleted subvolumes waiting to be cleaned, the trees are
    now looked up in radix tree instead of a O(N^2) search

    - snapshot creation with inherited qgroup will mark the qgroup
    inconsistent, requires a rescan

    - send will emit file capabilities after chown, this produces a
    stream that does not need postprocessing to set the capabilities
    again

    - direct io ported to iomap infrastructure, cleaned up and simplified
    code, notably removing last use of struct buffer_head in btrfs code

    Core changes:

    - factor out backreference iteration, to be used by ordinary
    backreferences and relocation code

    - improved global block reserve utilization
    * better logic to serialize requests
    * increased maximum available for unlink
    * improved handling on large pages (64K)

    - direct io cleanups and fixes
    * simplify layering, where cloned bios were unnecessarily created
    for some cases
    * error handling fixes (submit, endio)
    * remove repair worker thread, used to avoid deadlocks during
    repair

    - refactored block group reading code, preparatory work for new type
    of block group storage that should improve mount time on large
    filesystems

    Cleanups:

    - cleaned up (and slightly sped up) set/get helpers for metadata data
    structure members

    - root bit REF_COWS got renamed to SHAREABLE to reflect the that the
    blocks of the tree get shared either among subvolumes or with the
    relocation trees

    Fixes:

    - when subvolume deletion fails due to ENOSPC, the filesystem is not
    turned read-only

    - device scan deals with devices from other filesystems that changed
    ownership due to overwrite (mkfs)

    - fix a race between scrub and block group removal/allocation

    - fix long standing bug of a runaway balance operation, printing the
    same line to the syslog, caused by a stale status bit on a reloc
    tree that prevented progress

    - fix corrupt log due to concurrent fsync of inodes with shared
    extents

    - fix space underflow for NODATACOW and buffered writes when it for
    some reason needs to fallback to COW mode"

  • 9243c6f3e   block: Document genhd capability flags ... Browse Code »

    The kernel documentation includes a brief section about genhd
    capabilities, but it turns out that the only documented
    capability (GENHD_FL_MEDIA_CHANGE_NOTIFY) isn't used any more.

    This patch removes that flag, and documents the rest, based on my
    understanding of the current uses of these flags in the kernel. The
    documentation is kept in the header file, alongside the declarations,
    in the hope that it will be kept up-to-date in future; the kernel
    documentation is changed to include the documentation generated from
    the header file.

    Because the ultimate goal is to provide some end-user
    documentation (or end-administrator documentation), the comments are
    perhaps more user-oriented than might be expected. Since the values
    are shown to users in hexadecimal, the documentation lists them in
    hexadecimal, and the constant declarations are adjusted to match.

  • b68663186   block: add iostat counters for flush requests ... Browse Code »

    Requests that triggers flushing volatile writeback cache to disk (barriers)
    have significant effect to overall performance.

    Block layer has sophisticated engine for combining several flush requests
    into one. But there is no statistics for actual flushes executed by disk.
    Requests which trigger flushes usually are barriers - zero-size writes.

    This patch adds two iostat counters into /sys/class/block/$dev/stat and
    /proc/diskstats - count of completed flush requests and their total time.

  • 8060c47ba   block: rename CONFIG_DEBUG_BLK_CGROUP to CONFIG_BFQ_CGROUP_DEBUG ... Browse Code »

    This option is entirely bfq specific, give it an appropinquate name.

    Also make it depend on CONFIG_BFQ_GROUP_IOSCHED in Kconfig, as all
    the functionality already does so anyway.

  • 14ccb66b3   block: remove the bi_phys_segments field in struct bio ... Browse Code »

    We only need the number of segments in the blk-mq submission path.
    Remove the field from struct bio, and return it from a variant of
    blk_queue_split instead of that it can passed as an argument to
    those functions that need the value.

    This also means we stop recounting segments except for cloning
    and partial segments.

    To keep the number of arguments in this how path down remove
    pointless struct request_queue arguments from any of the functions
    that had it and grew a nr_segs argument.

  • 99c8b231a   docs: cgroup-v1: convert docs to ReST and rename to *.rst ... Browse Code »

    Convert the cgroup-v1 files to ReST format, in order to
    allow a later addition to the admin-guide.

    The conversion is actually:
    - add blank lines and identation in order to identify paragraphs;
    - fix tables markups;
    - add some lists markups;
    - mark literal blocks;
    - adjust title markups.

    At its new index.rst, let's add a :orphan: while this is not linked to
    the main index.rst file, in order to avoid build warnings.
