  • 27174203f   xfs: cleanup uuid handling ... Browse Code »

    The uuid table handling should not be part of a semi-generic uuid library
    but in the XFS code using it, so move those bits to xfs_mount.c and
    refactor the whole glob to make it a proper abstraction.

  • efc557570   [XFS] avoid memory allocations in xfs_fs_vcmn_err ... Browse Code »

    xfs_fs_vcmn_err can be called under a spinlock, but does a sleeping memory
    allocation to create buffer for it's internal sprintf. Fortunately it's
    the only caller of icmn_err, so we can merge the two and have one single
    static buffer and spinlock protecting it. While we're at it make sure
    we proper __attribute__ format annotations so that the compiler can detect
    mismatched format strings.

  • 9f8868ffb   [XFS] streamline init/exit path ... Browse Code »

    Currently the xfs module init/exit code is a mess. It's farmed out over a
    lot of function with very little error checking. This patch makes sure we
    propagate all initialization failures properly and clean up after them.
    Various runtime initializations are replaced with compile-time
    initializations where possible to make this easier. The exit path is
    similarly consolidated.

    There's now split out function to create/destroy the kmem zones and
    alloc/free the trace buffers. I've also changed the ktrace allocations to
    KM_MAYFAIL and handled errors resulting from that.

    And yes, we really should replace the XFS_*_TRACE ifdefs with a single
    XFS_TRACE..

  • d23415412   [XFS] Use power-of-2 sized buffers to reduce overhead ... Browse Code »

    Now that the ktrace_enter() code is using atomics, the non-power-of-2
    buffer sizes - which require modulus operations to get the index - are
    showing up as using substantial CPU in the profiles.

    Force the buffer sizes to be rounded up to the nearest power of two and
    use masking rather than modulus operations to convert the index counter to
    the buffer index. This reduces ktrace_enter overhead to 8% of a CPU time,
    and again almost halves the trace intensive test runtime.

    ktrace_enter() is consuming vast amounts of CPU time due to the use of a
    single global lock for protecting buffer index increments. Change it to
    use per-buffer atomic counters - this reduces ktrace_enter() overhead
    during a trace intensive test on a 4p machine from 58% of all CPU time to
    12% and halves test runtime.

  • ee5c80239   [XFS] fix ASSERT and ASSERT_ALWAYS ... Browse Code »

    - remove the != 0 inside the unlikely in ASSERT_ALWAYS because sparse now
    complains about comparisons between pointers and 0
    - add a standalone ASSERT implementation because defining it to
    ASSERT_ALWAYS means the string is expanded before the token passing
    stringification. This way we get the actual content of the
    assertion in the assfail message and don't overflow sparse's
    stringification buffer leading to sparse error messages.

  • 7989cb8ef   [XFS] Keep stack usage down for 4k stacks by using noinline. ... Browse Code »

    gcc-4.1 and more recent aggressively inline static functions which
    increases XFS stack usage by ~15% in critical paths. Prevent this from
    occurring by adding noinline to the STATIC definition.

    Also uninline some functions that are too large to be inlined and were
    causing problems with CONFIG_FORCED_INLINING=y.

    Finally, clean up all the different users of inline, __inline and
    __inline__ and put them under one STATIC_INLINE macro. For debug kernels
    the STATIC_INLINE macro uninlines those functions.

    The message buffer used by cmn_err() is only 256 bytes and some CXFS
    messages were exceeding this length. Since we were using vsprintf() and
    not checking for buffer overruns we were clobbering memory beyond the
    buffer. The size of the buffer has been increased to 1024 bytes so we can
    capture these larger messages and we are now using vsnprintf() to prevent
    overrunning the buffer size.

    This patch switches XFS over to use the new mutex code directly as
    opposed to the previous workaround patch I posted earlier that avoided
    the namespace clash by forcing it back to semaphores. This falls in the
    'works for me' category.

    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!
