Alexander Potapenko 741d9ecacc FROMGIT: tracing: add error_report_end trace point ... Patch series "Add error_report_end tracepoint to KFENCE and KASAN", v3. This patchset adds a tracepoint, error_repor_end, that is to be used by KFENCE, KASAN, and potentially other bug detection tools, when they print an error report. One of the possible use cases is userspace collection of kernel error reports: interested parties can subscribe to the tracing event via tracefs, and get notified when an error report occurs. This patch (of 3): Introduce error_report_end tracepoint. It can be used in debugging tools like KASAN, KFENCE, etc. to provide extensions to the error reporting mechanisms (e.g. allow tests hook into error reporting, ease error report collection from production kernels). Another benefit would be making use of ftrace for debugging or benchmarking the tools themselves. Should we need it, the tracepoint name leaves us with the possibility to introduce a complementary error_report_start tracepoint in the future.
