Not sure I understand. probe-file.h explicitly calls out a need for libelf due to the probe cache and related routines - commit 40218daea1db1 ("perf list: Show SDT and pre-cached events"). However, if you prefer to retain the ftrace README scanning here, we can drop this patch and I can update patch 6 to check for libelf. Thanks, Naveen
