Subject: [PATCH 05/11] qapi/gen: use './builtin' for the built-in module name
Date: Fri, 18 Dec 2020 21:54:01 +0100	[thread overview]
Message-ID: <20201218205407.1326907-6-armbru@redhat.com> (raw)
In-Reply-To: <20201218205407.1326907-1-armbru@redhat.com>

From: John Snow <jsnow@redhat.com>

Use this in preference to 'None', which helps remove some edge cases in
the typing.
