Date: Thu, 19 Oct 2017 11:17:05 +0800 From: Cao jin <caoj.fnst@...fujitsu.com> To: <linux-kernel@...r.kernel.org>, <linux-doc@...r.kernel.org>, <linux-kbuild@...r.kernel.org> CC: <corbet@....net>, <mmarek@...e.com>, <yamada.masahiro@...ionext.com> Subject: [PATCH] kbuild doc: a bundle of fixes on makefiles.txt It does several fixes: 1. move the displaced ld example to its reasonale place. 2. add new example for command gzip. 3. fix 2 number errors. 4. fix format of chapter 7.x, make it looks the same as other chapters.
