It appears this patch changes the sha1 of some programs, but not some other programs. For example, sha1 of program test_task_kfunc_flavor_relo_not_found from task_kfunc_success.bpf.o stays the same before and after the patch, while other programs from task_kfunc_success.bpf.o have different sha1 after the patch. Is this expected? Thanks, Song
