From d2e04b9dd617ceaebf4f0ce6a3daf039bc08895e Mon Sep 17 00:00:00 2001 From: Lukas Bulwahn Date: Mon, 18 Jan 2021 09:00:04 +0100 Subject: [PATCH] docs, bpf: Add minimal markup to address doc warning Commit 91c960b00566 ("bpf: Rename BPF_XADD and prepare to encode other atomics in .imm") modified the BPF documentation, but missed some ReST markup. Hence, make htmldocs warns on Documentation/networking/filter.rst:1053: WARNING: Inline emphasis start-string without end-string. Add some minimal markup to address this warning.
