  • a9273ca5c   xfs: convert attr to use unsigned names ... Browse Code »

    To be consistent with the directory code, the attr code should use
    unsigned names. Convert the names from the vfs at the highest level
    to unsigned, and ænsure they are consistenly used as unsigned down
    to disk.

  • 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:

  • e82fa0c7c   xfs: rename xfs_attr_fetch to xfs_attr_get_int ... Browse Code »

    Using a totally different name for the low-level get operation does
    not fit the _int convention used in the rest of the attr code, so
    rename it.

    While we're at it also fix the prototype to use the normal convention
    and mark it static as it's never used outside of xfs_attr.c.

  • e182f57ac   [XFS] attrmulti cleanup ... Browse Code »

    xfs_attrmulti_by_handle currently request the size based on
    sizeof(attr_multiop_t) but should be using sizeof(xfs_attr_multiop_t)
    because that is what it is dealing with. Despite beeing wrong this
    actually harmless in practice because both structures are the same size on
    all platforms.

    But this sizeof was the only user of struct attr_multiop so we can just
    kill it. Also move the ATTR_OP_* defines xfs_attr.h into the struct
    xfs_attr_multiop defintion in xfs_fs.h because they are only used with
    that structure, and are part of the user ABI for the
    XFS_IOC_ATTRMULTI_BY_HANDLE ioctl.

    a separate boolean for error handling. Thanks to Dave Chinner for that
    fix.

    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!
