From aa8dbeee5ee012e1ee595dd1df9be04e161a3fd4 Mon Sep 17 00:00:00 2001 From: Yann Droneaud Date: Sun, 13 Jul 2014 12:15:29 +0200 Subject: Documentation: headers_install.txt is part of kbuild 'headers_install.txt' from Documentation/make/ is related to Kbuild so it must be moved in Documentation/kbuild/ directory. As Documentation/make/ directory has only one file, it will be removed as a consequence of moving 'headers_install.txt'. Cc: Kirill A.
