That would be the best, as we > would then reduce the need for audit-libs to be linked with perf. It looks similar to x86 but at the time being, s390 does not have a system call table like x86. So the input is different, the output will follow what x86 provides to perf. > > We really need to reduce the number of libraries that perf links to :-\ I have prepared two patches to get rid of the auditlibs dependency for those arch's that have system call tables. Going to post this today. Thanks and kind regards, Hendrik
