To do so, we define flags on a set of kfuncs as follows:: - BTF_SET8_START(bpf_task_set) + BTF_KFUNCS_START(bpf_task_set) BTF_ID_FLAGS(func, bpf_get_task_pid, KF_ACQUIRE | KF_RET_NULL) BTF_ID_FLAGS(func, bpf_put_pid, KF_RELEASE) - BTF_SET8_END(bpf_task_set) + BTF_KFUNCS_END(bpf_task_set) This set encodes the BTF ID of each kfunc listed above, and encodes the flags along with it. Ofcourse, it is also allowed to specify no flags. @@ -347,10 +347,10 @@ Once the kfunc is prepared for use, the final step to making it visible is registering it with the BPF subsystem.
