H A D | trampoline.c | b91e014f Mon Dec 09 00:01:13 GMT 2019 Alexei Starovoitov <ast@kernel.org> bpf: Make BPF trampoline use register_ftrace_direct() API
Make BPF trampoline attach its generated assembly code to kernel functions via register_ftrace_direct() API. It helps ftrace-based tracers co-exist with BPF trampoline on the same kernel function. It also switches attaching logic from arch specific text_poke to generic ftrace that is available on many architectures. text_poke is still necessary for bpf-to-bpf attach and for bpf_tail_call optimization.
