Subject[PATCH v2 0/2] perf probe: fix regression introduced by switch to die_get_decl_file
Date
When switching from dwarf_decl_file() to die_get_decl_file(), a regression
was introduced when having a binary where the DWARF info is split to
multiple CUs. It is not possible to add probes to certain functions.

These patches introduce a testcase which shows the current regression
and a fix for the issue
