# need the function prototype(s) in bpf_lsm_proto.o to take precedence
# over those within bpf_lsm.o. Having bpf_lsm_proto.o precede
# bpf_lsm.o ensures its DWARF CU is processed early, forcing the
# generated BTF to contain the overrides.
#
# Notably, this is a temporary workaround whilst the deduplication
# semantics within pahole are revisited accordingly.
