Hi Shuah,

This was due to a newline at the end of:
tools/testing/selftests/futex/functional/run.sh

Which unfortunately checkpatch.pl doesn't catch. My fault for not applying
the series from the generated patches first. Sorry for the hassle.

I have corrected this in the first patch and pushed v3 of the series to:

git://git.infradead.org/users/dvhart/linux.git futextest-v3


$ git diff infradead/futextest-v2 infradead/futextest-v3
diff --git a/tools/testing/selftests/futex/functional/run.sh
b/tools/testing/selftests/futex/functional/run.sh
index 46827a8..e87dbe2 100755
--- a/tools/testing/selftests/futex/functional/run.sh
+++ b/tools/testing/selftests/futex/functional/run.sh
@@ -77,4 +77,3 @@ echo
echo
./futex_wait_uninitialized_heap $COLOR
./futex_wait_private_mapped_file $COLOR
-

Is this sufficient or do would you prefer a new pull request?

Thanks,
