[PATCH 00/20] MODULE_LICENSE removals, fifth tranche

[PATCH 00/20] MODULE_LICENSE removals, fifth tranche

[Nick Alcock]

This series, based on current modules-next, is part of a treewide cleanup
suggested by Luis Chamberlain, to remove the LICENSE_MODULE usage from
files/objects that are not tristate.  Due to recent changes to kbuild, these
uses are now problematic.  See the commit logs for more details.

(The commit log prefixes and Cc lists are automatically determined.  I've
eyeballed them, and they seem reasonable: my apologies if they are not.)

I'll be sending a sixth and final tranche in a few days. (In total, there are 121
patches in this series.)


The series at a whole can be found here:
  https://github.com/nickalcock/linux module-license

(This is a respin with kbuild: prefixes dropped.  The previous series,
used in the mailouts of tranche 3 and earlier, is in the
module-license-kbuild-prefix branch.)

[PATCH 14/20] rv/reactor: remove MODULE_LICENSE in non-modules

[Nick Alcock]

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

Does this mean you expect us to queue them for v6.3?
Thanks!

I believe Luis is planning to pull them in around -rc3, hence my
freshening the series up now, getting everyone's tags in, etc.

Why isn't kbuild fixed instead?  These files can have MODULE_AUTHOR()
and other macros when built into the kernel, what is so special about
MODULE_LICENSE() that prevents this from working properly?

There should not be a need to remove these markings in my opinion, why
treat one MODULE_* macro more special than others?

thanks,
