Now only elf btf can be placed in the default path(/boot), raw btf should also can be there.
There are more default paths than just /boot. Also some grammer issues in the above like 'should also can be'. Maybe the commit message can be changed like below. Currently, the default vmlinux files at '/boot/vmlinux-*', '/lib/modules/*/vmlinux-*' etc. are parsed with 'btf__parse_elf' to extract BTF. It is possible that these files are actually raw BTF files similar to /sys/kernel/btf/vmlinux. So parse these files with 'btf__parse' which tries both raw format and ELF format. It would be great if you can add more information on why '/boot/vmlinux-*' or '/lib/modules/*/vmlinux-*' might be a raw BTF file in your system.
