I do not find it ready, for example elf_backend_write_core_note should be also changed etc. Feel free to take it. So far pushing/committing patches more ready for upstreaming when I find the time. Also even if it would be pushed I find this new testcase to make more safe by relying on the more established kernel core files producer. It was only a bit but still tricky to find out this dependency for me before. Thanks, Jan ^ permalink raw reply [flat|nested] 6+ messages in thread
