Thanks for this. In general it looks good, there is just one failure worrying me a bit: https://autobuilder.yoctoproject.org/typhoon/#/builders/119/builds/425 which in diffoscope speak is: http://autobuilder.yocto.io/pub/repro-fail/oe-reproducible-20210702-c3hu90kc/packages/diff-html/ You may wonder what this pull request has to do with a gcc-sanitisers failure? If you don't speak dwarfish or elvish, it means that perf_branch_sample_type_shift was declared on line 162 in one build and 182 in another. I wondered about a bit flip however it is two bits and linux/perf_events.h has perf_branch_sample_type_shift at line number 162 in 5.10 and 182 is 5.13 and that file comes from linux-libc-headers. The logical conclusion is that one was built with one header and the other, from the other header. Why/how this could happen I simply don't know. The problem build came from sstate so there is no real audit trail to follow :(. I'm not sure this blocks the pull request as the issue is probably somewhere else and this just exposed it but any ideas on what happened are very welcome... Cheers, Richard
