+#
+# - bugprone-reserved-identifier
+#   Some macros need to be defined for portability purpose; e.g. _BSD_SOURCE.
+#
+# - google-upgrade-googletest-case
+#   This requires googletest 1.10 which is higher than ones installed on many linux distributions.
+#
+# - modernize-redundant-void-arg
+#   Some source should be strictly C99 and func(void) should be used.
+#
+# Note on checks which will be enabled in future. These are good to have but
+# it's not activated yet due to the existing issues with the checks.
+# Once those issues are clear, these checks can be enabled later.
