+Subject: [rhel-only PATCH] revert Confine irqbalance to systems where it is useful.
+
+ConditionCPUs only available from systemd(>=242), however the systemd
+version for rhel8 is 239. So we need to revert the patch, otherwise we
+will encounter the failing:
+
+    $ sudo systemd-analyze verify irqbalance.service
+    /usr/lib/systemd/system/irqbalance.service:6: Unknown lvalue
+    'ConditionCPUs' in section 'Unit'
+
+This patch revert 188f9efc567bcaef25bde2813cdee7f952f992f9.
