Describe changes:
The use of
SUBDIRS
to specify the location of external module source files has been deprecated since Linux kernel version 5.3. It caused unintended file deletion in my Linux 6.8.1 source tree. The recommended replacement is to useM
instead.This commit updates the Makefile to use
M=$(HERE)
instead ofSUBDIRS=$(HERE)
in the 'clean' target. This change ensures compatibility with newer Linux kernels and avoids potential issues during the build process, such as the unintended deletion of files.
