Since common_callchain has been added to the argument array, we need to reflect it in perl-based scripts, because otherwise the following args would be shifted and thus incorrect. E.g. rw-by-pid and calculation of read and written bytes: Before: read counts by pid: pid comm # reads bytes_requested bytes_read ------ -------------------- ----------- ---------- ---------- 19301 dd 4 424510450039736 0 After: read counts by pid: pid comm # reads bytes_requested bytes_read ------ -------------------- ----------- ---------- ---------- 19301 dd 4 9536 4341 Committer testing: To see before after first do: # perf script record rw-by-pid ^C Now you'll have a perf.data file to report on, then do before and after using: # perf script report rw-by-pid Anbd notice the bytes_request/bytes_read, as above.
