  • ea15ab3cd   xfs: remove the dead QUOTADEBUG code ... Browse Code »

    Remove the dead hash table test rid which has been rotting away under
    QUOTADEBUG, including some code that was compiled for normal debug
    builds, but not actually called without QUOTADEBUG, and enable a few
    cheap debug checks that were hidden under QUOTADEBUG for normal
    debug builds.

  • 0b1b213fc   xfs: event tracing support ... Browse Code »

    Convert the old xfs tracing support that could only be used with the
    out of tree kdb and xfsidbg patches to use the generic event tracer.

    To use it make sure CONFIG_EVENT_TRACING is enabled and then enable
    all xfs trace channels by:

    echo 1 > /sys/kernel/debug/tracing/events/xfs/enable

    or alternatively enable single events by just doing the same in one
    event subdirectory, e.g.

    echo 1 > /sys/kernel/debug/tracing/events/xfs/xfs_ihold/enable

    or set more complex filters, etc. In Documentation/trace/events.txt
    all this is desctribed in more detail. To reads the events do a

    cat /sys/kernel/debug/tracing/trace

    Compared to the last posting this patch converts the tracing mostly to
    the one tracepoint per callsite model that other users of the new
    tracing facility also employ. This allows a very fine-grained control
    of the tracing, a cleaner output of the traces and also enables the
    perf tool to use each tracepoint as a virtual performance counter,
    allowing us to e.g. count how often certain workloads git various
    spots in XFS. Take a look at

    http://lwn.net/Articles/346470/

    for some examples.

    Also the btree tracing isn't included at all yet, as it will require
    additional core tracing features not in mainline yet, I plan to
    deliver it later.

    And the really nice thing about this patch is that it actually removes
    many lines of code while adding this nice functionality:

    Commit e687330b5ed1ea899fdaf0dea50aba196b6e019a was meant to remove the
    unused HAVE_SPLICE macro, instead an unrelated change was checked enabling
    QUOTADEBUG when building DEBUG XFS. Restore the intended changes.

  • 2a82b8be8   [XFS] Concurrent Multi-File Data Streams ... Browse Code »

    In media spaces, video is often stored in a frame-per-file format. When
    dealing with uncompressed realtime HD video streams in this format, it is
    crucial that files do not get fragmented and that multiple files a placed
    contiguously on disk.

    When multiple streams are being ingested and played out at the same time,
    it is critical that the filesystem does not cross the streams and
    interleave them together as this creates seek and readahead cache miss
    latency and prevents both ingest and playout from meeting frame rate
    targets.

    This patch set creates a "stream of files" concept into the allocator to
    place all the data from a single stream contiguously on disk so that RAID
    array readahead can be used effectively. Each additional stream gets
    placed in different allocation groups within the filesystem, thereby
    ensuring that we don't cross any streams. When an AG fills up, we select a
    new AG for the stream that is not in use.

    The core of the functionality is the stream tracking - each inode that we
    create in a directory needs to be associated with the directories' stream.
    Hence every time we create a file, we look up the directories' stream
    object and associate the new file with that object.

    Once we have a stream object for a file, we use the AG that the stream
    object point to for allocations. If we can't allocate in that AG (e.g. it
    is full) we move the entire stream to another AG. Other inodes in the same
    stream are moved to the new AG on their next allocation (i.e. lazy
    update).

    Stream objects are kept in a cache and hold a reference on the inode.
    Hence the inode cannot be reclaimed while there is an outstanding stream
    reference. This means that on unlink we need to remove the stream
    association and we also need to flush all the associations on certain
    events that want to reclaim all unreferenced inodes (e.g. filesystem
    freeze).

  • 733482e44   [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason ... Browse Code »

    This patch removes almost all inclusions of linux/version.h. The 3
    #defines are unused in most of the touched files.

    A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
    unfortunatly in linux/version.h.

    There are also lots of #ifdef for long obsolete kernels, this was not
    touched. In a few places, the linux/version.h include was move to where
    the LINUX_VERSION_CODE was used.

    quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`

    search pattern:
    /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
