From cacad346f67ce9604dcc9db10f1f1769dabb3891 Mon Sep 17 00:00:00 2001 From: David Vernet Date: Thu, 2 Mar 2023 12:39:18 -0600 Subject: [PATCH] bpf, docs: Fix final bpf docs build failure maps.rst in the BPF documentation links to the /userspace-api/ebpf/syscall document (Documentation/userspace-api/ebpf/syscall.rst). For some reason, if you try to reference the document with :doc:, the docs build emits the following warning: ./Documentation/bpf/maps.rst:13: WARNING: \ unknown document: '/userspace-api/ebpf/syscall' It appears that other places in the docs tree also don't support using :doc:. Elsewhere in the BPF documentation, we just reference the kernel docs page directly. Let's do that here to clean up the last remaining noise in the docs build.
