      Description

      The behavior of "perf probe" has changed. It does not respect the names you give to your trace points anymore. In particular

      • It adds a suffix "__return" to any trace points for <function>%return.
      • It can create multiple trace point from one "perf probe -x" call, adding _<i> to the name with i being a number.

      It seems perf probe is not meant to be used in automated scripts.
