Hi,
This is the 2nd version of the multiprobe support on perf probe.
This can be applied on top of perf/core.
Inlined functions or the lines which have multiple statements can be compiled in multiple addresses. Current perf probe generates different events for each address, but this is not useful for users.
Since ftrace multiprobe per event support is on upstream kernel, it is a time to push this series. In this version, I have updated the [1/4] not to add suffix _L* if user doesn't specify the line number for the function or the line number is 0. And also, [4/4] is updated according to [1/4] change.
The previous version is here.

Thank you,
