| |
bpf_jit_comp64.c uses patch_text(), so add <asm/patch.h> to it to prevent the build error:
../arch/riscv/net/bpf_jit_comp64.c: In function 'bpf_arch_text_poke': ../arch/riscv/net/bpf_jit_comp64.c:691:23: error: implicit declaration of function 'patch_text'; did you mean 'path_get'? [-Werror=implicit-function-declaration] 691 | ret = patch_text(ip, new_insns, ninsns); | ^~~~~~~~~~
