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,
