Since commit 1b8abbb ("bpf...d_path(): constify path argument"), the first parameter of the bpf_d_path() has been changed to a const constant. We need to modify the header file and bpf_doc.py. The two error messages are as follows: linux/tools/testing/selftests/bpf$ make CLNG-BPF [test_progs] bpf_iter_task_vmas.bpf.o progs/bpf_iter_task_vmas.c:52:14: error: passing 'const struct path *' to parameter of type 'struct path *' discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers] 52 | bpf_d_path(&file->f_path, d_path_buf, D_PATH_BUF_SIZE); | ^~~~~~~~~~~~~ 1 error generated. .... progs/verifier_vfs_accept.c:80:7: error: assigning to 'struct path *' from 'const struct path *' discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers] 80 | path = &file->f_path; | ^ ~~~~~~~~~~~~~ 1 error generated.
