    Subject[PATCH perf/core v11 00/23] perf-probe --cache and SDT support
    Date
    Hi,

    Resend: Sorry, I missed some last patches...

    Here is the 11th version of the patchset for probe-cache and
    initial SDT support.

    Here is the previous v10: https://lkml.org/lkml/2016/6/8/318
    And v9: https://lkml.org/lkml/2016/5/28/103

    This version fixes some bugs and changes codes according to
    Arnaldo's comments.

    Changes in v11:
    - [06/23]: Make probe_cache_entry__delete() to check NULL and
    do not list_del().
    - [06/23]: Rename functions and members and check some return
    values according to Arnaldo's review.
    - [07/23]: Check failure of probe_cache operations and warn it.
    - [09/23]: build_id_cache__list_all() is hardened and returns
    strlist directly instead of error code.
    - [10/23]: Fix to check cache is purged and rename remove func to
    probe_cache__filter_purge().
    - [13/23]: Warn if SDT scanning/updating are failed.

    Thank you,
