    Subject[STABILITY] Compile / STP metrics
    From
    Date
    Compile statistics have been for kernel releases from 2.5.46 to 2.5.54
    at: www.osdl.org/archive/cherry/stability

    This page also has the beginnings of STP (Scalable Test Platform)
    results for a number of tests (aim9, LTP, unixbench, contest, bonnie++,
    debench (quick), hackbench, iozone, dbt1 (1-tier), lmbench (short)) for
    recent kernel releases.

    These metrics are simply one way to measure how 2.5 is converging. Many
    of the compilation errors are being addressed by various kernel
    developers, so in some ways, these statics are restating the obvious.

    Reasonable convergence of compile time warnings/errors was happening
    until 2.5.54 was released. However, 2.5.54 took a step backwards. The
    latest results show...

    2.5.53 2.5.54
    ------------------------ ------------------------
    bzImage (defconfig) 16 warnings/0 errors 68 warnings/0 errors
    bzImage (allmodconfig) 31 warnings/9 errors 40 warnings/11 errors
    modules (allmodconfig) 1843 warnings/118 errors 3223 warnings/208 errors

    The script that generated this data is also at
    www.osdl.org/archive/cherry/stability. Detailed information on warnings
    and errors can be found by following the links in the table, but a
    summary of the 2.5.54 run is shown here....
