Subject: [PATCH] kbuild: doc: remove documentation about copying Module.symvers around
Date: Thu, 21 May 2020 13:31:17 +0900 [thread overview]

This is a left-over of commit 39808e451fdf ("kbuild: do not read

- Use an extra Module.symvers file

- from bar.ko, copy the Module.symvers file from the

Use "make" variable KBUILD_EXTRA_SYMBOLS
If it is impractical to add a top-level kbuild file,
you can assign a space separated list
