Currently, BPF programs typically have a suffix of .bpf.c. However, some programs still utilize a mixture of _kern.c suffix alongside the naming convention. In order to achieve consistency in the naming of these programs, this commit unifies the inconsistency in the naming convention of BPF kernel programs. Signed-off-by: Daniel T.
