From cffe57bee62b155c08d71218fc0e9e84a0a90bbb Mon Sep 17 00:00:00 2001 From: Bagas Sanjaya Date: Wed, 22 Jun 2022 15:45:46 +0700 Subject: [PATCH] Documentation: highmem: use literal block for code example in highmem.h comment When building htmldocs on Linus's tree, there are inline emphasis warnings on include/linux/highmem.h: Documentation/vm/highmem:166: ./include/linux/highmem.h:154: WARNING: Inline emphasis start-string without end-string. Documentation/vm/highmem:166: ./include/linux/highmem.h:157: WARNING: Inline emphasis start-string without end-string. These warnings above are due to comments in code example at the mentioned lines above are enclosed by double dash (--), which confuses Sphinx as inline markup delimiters instead. Fix these warnings by indenting the code example with literal block indentation and making the comments C comments.
