            Bug ID: 31638
           Summary: Recognize (and skip) bpf (kernel) files
           Product: debugedit
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: find-debuginfo
          Assignee: unassigned at sourceware dot org
          Reporter: mark at klomp dot org
                CC: debugedit at sourceware dot org
  Target Milestone: ---

find-debuginfo thinks the BPF files are "normal" ELF files and calls
gdb-add-index on them. But the BPF files aren't "normal" and don't have any
debuginfo. So gdb-add-index fails.

See e.g.
https://kojipkgs.fedoraproject.org//packages/kernel/6.8.5/301.fc40/data/logs/x86_64/build.log
