Subject: Re: [PATCH] fix missing 'sys' package

Hi Kortan,

Thank you for the patch! I have some comments inline.

The commit title/subject should have a prefix to it. You can see the
prefix for this particular file by running:

$ git log --oneline --format=%s scripts/clang-tools/gen_compile_commands.py
gen_compile_commands: extract compiler command from a series of commands
gen_compile_commands: prune some directories
scripts/clang-tools: switch explicitly to Python 3
Makefile: Add clang-tidy and static analyzer support to makefile

So your commit title would be:

gen_compile_commands: fix missing 'sys' package

There needs to be a message here. It is obvious once you look at the
file that we call sys.exit() so we need the import but that needs to be
explained up front here. checkpatch.pl would have warned you about this:

WARNING: Missing commit description - Add an appropriate one

total: 0 errors, 1 warnings, 7 lines checked

Otherwise, the change looks good to me. Please make these corrections
and send a v2 of the patch, which can be done with the '-v#' flag to
'git format-patch' (e.g. '-v2' in this case).

Describe the diff between v1 and v2 here like:

v1 -> v2:

* Fix commit title

* Improve commit message

then be sure to also include Masahiro Yamada and the linux-kbuild
mailing list as he will pick up the patch.

Masahiro Yamada <masahiroy@...nel.org>
linux-kbuild@...r.kernel.org

Please use our new mailing list as well:

llvm@...ts.linux.dev

Cheers,
Nathan
