  • b4e9181e7   xfs: remove unused delta tracking code in xfs_bmapi ... Browse Code »

    This code was introduced four years ago in commit
    3e57ecf640428c01ba1ed8c8fc538447ada1715b without any review and has
    been unused since. Remove it just as the rest of the code introduced
    in that commit to reduce that stack usage and complexity in this central
    piece of code.

  • 288699fec   xfs: drop dmapi hooks ... Browse Code »

    Dmapi support was never merged upstream, but we still have a lot of hooks
    bloating XFS for it, all over the fast pathes of the filesystem.

    This patch drops over 700 lines of dmapi overhead. If we'll ever get HSM
    support in mainline at least the namespace events can be done much saner
    in the VFS instead of the individual filesystem, so it's not like this
    is much help for future work.

  • 7b6259e7a   xfs: remove block number from inode lookup code ... Browse Code »

    The block number comes from bulkstat based inode lookups to shortcut
    the mapping calculations. We ar enot able to trust anything from
    bulkstat, so drop the block number as well so that the correct
    lookups and mappings are always done.

  • 657a4cffd   xfs: replace E2BIG with EFBIG where appropriate ... Browse Code »

    Many places in the xfs code return E2BIG when they really mean
    EFBIG; trying to grow past 16T on a 32 bit machine, for example,
    says "Argument list too long" rather than "File too large" which is
    not particularly helpful.

    Some of these don't make perfect sense as EFBIG either, but still
    better than E2BIG IMHO.

  • 3daeb42c1   xfs: fix missing error check in xfs_rtfree_range ... Browse Code »

    When xfs_rtfind_forw() returns an error, the block is returned
    uninitialised. xfs_rtfree_range() is not checking the error return,
    so could be using an uninitialised block number for modifying bitmap
    summary info.

    The problem was found by gcc when compiling the *userspace* libxfs
    code - it is an copy of the kernel code with the exact same bug.
    gcc gives an uninitialised variable warning on the userspace code
    but not on the kernel code. You gotta love the consistency (Mmmm,
    slightly chewy today!).

  • 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:

  • 743bb4650   [XFS] Move copy_from_user calls out of ioctl helpers into ioctl switch. ... Browse Code »

    Moving the copy_from_user out of some of the ioctl helpers will
    make it easier for the compat ioctl switch to copy in the right
    struct, then just pass to the underlying helper.

    Also, move common access checks into the helpers themselves,
    and out of the native ioctl switch code, to reduce code
    duplication between native & compat ioctl callers.

  • 0924b585f   [XFS] fix uninitialised variable bug in dquot release. ... Browse Code »

    gcc is warning about an uninitialised variable in xfs_growfs_rt().
    This is a false positive. Fix it by changing the scope of the
    transaction pointer to wholly within the internal loop inside
    the function.

    While there, preemptively change xfs_growfs_rt_alloc() in the
    same way as it has exactly the same structure as xfs_growfs_rt()
    but gcc is not warning about it. Yet.

    xfs_trans_commit() can return errors when there are problems in the
    transaction subsystem. They are indicative that the entire transaction may
    be incomplete, and hence the error should be propagated as there is a good
    possibility that there is something fatally wrong in the filesystem. Catch
    and propagate or warn about commit errors in the places where they are
    currently ignored.

    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!
