Commit Message

Nick Alcock Feb. 24, 2023, 3:07 p.m. UTC
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.

Applied as well. Squashed with next one. Same subject messes with b4, so
prefix should be corrected if these were to stay as separate patches.

Best regards,

And all dropped. Run checkpatch before sending patches.

So... which of the 27 patches n this series is being dropped? It would
also be nice to know what the checkpatch problems were, because all I
can see from checkpatch is one error per patch, an apparent false
positive:

ERROR: Please use git commit description style 'commit <12+ chars of sha1> ("<title line>")' - ie: 'commit 8b41fc4454e3 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf")'

The commit message says:

> Since commit 8b41fc4454e ("kbuild: create modules.builtin without
> Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations

... which unless I am seeing things is precisely what checkpatch.pl is
asking for. Perhaps it can't handle wrapped lines, but not wrapping a
git commit log line *also* (correctly) elicits a checkpatch error...

The ones I responded that I applied - so the memory controller ones.

It's not a false positive, but an error I am asking fix (assuming there
are no more ones) There is no problem with wrapping lines - checkpatch
handles it.

OK, resent those three (now two), checkpatch-clean and fused identical
subjects together. (Not adjusted non-memory-controller patch commit
logs, to avoid causing disruption with those that are already flowing
into the tree.)

Hope this is better :)

If you send a new patch, mark it appropriately and include changelog.
