Hello there, Last year, libbpf added support for attaching multiple handlers to the same event by allowing defining multiple progs in the same elf section. However, the pin path for a bpf program is obtained via the __bpf_program__pin_name function, which uses an escaped version of the elf section name as the pin_name. Thus, trying to pin multiple bpf programs defined on the same section fails with "File exists" error, since libbpf tries to pin more than one program on a single path. Does adding the actual program name to the pin path makes sense? Thanks.
