+Subject: [PATCH] bpf: Finish constification of 1st parameter of bpf_d_path()
+
+The commit 1b8abbb12128 ("bpf...d_path(): constify path argument")
+constified the first parameter of the bpf_d_path(), but failed to
+update it in all places. Finish constification.
+
+Otherwise the selftest fail to build:
+.../selftests/bpf/bpf_experimental.h:222:12: error: conflicting types for 'bpf_path_d_path'
+  222 | extern int bpf_path_d_path(const struct path *path, char *buf, size_t buf__sz) __ksym;
+      |            ^
+.../selftests/bpf/tools/include/vmlinux.h:153922:12: note: previous declaration is here
+ 153922 | extern int bpf_path_d_path(struct path *path, char *buf, size_t buf__sz) __weak __ksym;
+
+Fixes: 1b8abbb12128 ("bpf...d_path(): constify path argument")
