    Subject[PATCH -tip 0/8] perf-probe updates
    Hi Ingo,

    Here are several bugfixes and updates of perf-probe and
    This updates includes --line option support which you are
    waiting for :-).

    For kprobe-tracer, I decided to drop $argN support, because
    the ABI for each function strongly depends on not only the
    architecture but also the API of the function and gcc options.
    Anyway, we already have perf-probe which allows us to find
    register/memory assignment of each arguments.

    Here are updated todo list.

    Long-term TODOs (future features):
    - Support lazy string matching(glob?) for selecting probing
    - Support sys_perf_counter_open (for non-root users)
    - Support tracing static variables (non global)
    - Support variable types from debuginfo (e.g. char, int, ...)
    - Support fields of data structures (var->field)
    - Support array (var[N])
    - Support dynamic array-indexing (var[var2])
    - Support string/dynamic arrays (*var, var[N..M])
    - Support force type-casting ((type)var)
    - Support the type of return value

    - Better support for probes on modules
    - Move onto libdw/libdwfl
    - Storing file name/line number information in the
    kernel for listing events

    Thank you,
