heya,
the change below 'fixes' it for me:
$ perf script ...
...
evince 2220122 1605573.007639: 11759 cycles:u:
ffffffffaec012f0 [unknown] ([unknown])
7f93f17116b6 __mmap64+0x26 mmap64.c:59 (inlined)
7f93f17116b6 __mmap64+0x26 mmap64.c:47 (inlined)
it wasn't really broken, the output is just missing the source line
info in perf script callchain output, which adds the "missing part",
because for inlined entries the entry address stays the same for all
its inlined parts
could you try the change?
thanks,
jirka
