	Since commit 040fcc819a2e ("kbuild: improved modversioning support for external modules"), the external module build reads Module.symvers in the directory of the module itself, then dumps symbols back into it. It accumulates stale symbols in the file when you build an external module incrementally. The idea behind it was, as the commit log explained, you can copy Modules.symvers from one module to another when you need to pass symbol information between two modules. However, the manual copy of the file sounds questionable to me, and containing stale symbols is a downside. Some time later, commit 0d96fb20b7ed ("kbuild: Add new Kbuild variable KBUILD_EXTRA_SYMBOLS") introduced a saner approach. So, this commit removes the former one. Going forward, the external module build dumps symbols into Module.symvers to be carried via KBUILD_EXTRA_SYMBOLS, but never reads it automatically. With the -I option removed, there is no one to set the external_module flag unless KBUILD_EXTRA_SYMBOLS is passed. Now the -i option does it instead.

2019-10-05	kbuild: two minor updates for Documentation/kbuild/modules.rst	Masahiro Yamada	1	-2/+2
	Capitalize the first word in the sentence. Use obj-m instead of obj-y. obj-y still works, but we have no built-in objects in external module builds. So, obj-m is better IMHO. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2019-09-10	modpost: add support for symbol namespaces	Matthias Maennich	1	-2/+5
	Add support for symbols that are exported into namespaces. For that, extract any namespace suffix from the symbol name. In addition, emit a warning whenever a module refers to an exported symbol without explicitly importing the namespace that it is defined in. This patch consistently adds the namespace suffix to symbol names exported into Module.symvers. Example warning emitted by modpost in case of the above violation: WARNING: module ums-usbat uses symbol usb_stor_resume from namespace USB_STORAGE, but does not import it.

2019-06-14	docs: kbuild: convert docs to ReST and rename to *.rst	Mauro Carvalho Chehab	1	-0/+571
	The kbuild documentation clearly shows that the documents there are written at different times: some use markdown, some use their own peculiar logic to split sections. Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
