Hi,

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,
