Hi all, Here is the initial support of probing sdt markers. This implementation still needs in functions to obtain list of all available markers, and also all available symbols (like perf) I think, to use patterns for example, however this can wait a little. Thanks. Contains next patches: [PATCH 1/4] symbol: add elf_section_by_name() helper (based on [PATCH 2/4] symbol: add helpers for sdt probes. [PATCH 3/4] stapsdt: initial support for probing sdt notes. [PATCH 4/4] scripts: add test script for stapstd probes
