This indeed looks much simpler and cleaner (as far as I can judge with my
limited kbuild knowledge). We just need to remove MODULE_INFO(livepatch,
"Y") from lib/livepatch/test_klp_convert_mod_a.c to make it compile and
work (test_klp_convert_mod_a is not a livepatch module, it is just a dummy
module which is then livepatched by lib/livepatch/test_klp_convert1.c).
Yeah, Masahiro this is great, thanks for reworking this!
I did tweak one module like Miroslav mentioned and I think a few of the
newly generated files need to be cleaned up as part of "make clean", but
all said, this is a nice improvement.
Well actually, now I see this comment in the top-level Makefile:
# Cleaning is done on three levels.
# make clean Delete most generated files
# Leave enough to build external modules
# make mrproper Delete the current configuration, and all generated
# make distclean Remove editor backup files, patch leftover files and
I didn't realize that we're supposed to be able to still build external
modules after "make clean". If that's the case, then one might want to
build an external klp-module after doing that.
With that in mind, shouldn't Symbols.list to persist until mrproper?
And I think modules-livepatch could go away during clean, what do you think?
