    Subject[PATCH perf/core v7 00/21] perf-probe --cache and SDT support
    Date
    Hi,

    Here is the 7th version of the patchset for probe-cache and
    initial SDT support.

    The previous version is here; https://lkml.org/lkml/2116/4/29/358

    This version add some bugfixes and cleanup patches. Also, tested
    by using runtests (https://github.com/mhiramat/runtests) which found
    several bugs in previous version.
    (I've added test.d/buildid-cache/*.tc, test.d/probe/cache*.tc and
    test.d/probe/sdt.tc for this series)

    Changes in v7:
    - [1/21]-[5/21], [7/21] Newly added for bugfix and cleanup.
    - [6/21] Remove unneeded local strlist.
    - [8/21] Move kallsyms buildid related code into build-id.c
    (as build_id_cache__kallsyms_path).
    - [11/21] Remove the top '/' from binary name if it is not a regular file.
    - [16/21] Fix a bug to return an error if no SDT/cached events found in cache.
    - [18/21] Validate build-id via sysfs if it is for kallsyms,
    - [19/21] Continue to search caches if a build-id cache has no probe cache.
    - [19/21] Make probe_cache__open() to accept DSO__NAME_KALLSYMS for kernel.
    - [19/21] Fix to add probes correctly when a wildcard matchs both of
    uprobes and kprobes.
    - [21/21] as Brendan suggested, special support for "sdt_" prefix
    (treat it as same as "%sdt_" )


    Thank you,
