Subject: [PATCH] git: introduce async_wait_all
Date: Sat, 17 Oct 2020 08:04:24 +0000 [thread overview]
Message-ID: <20201017080424.4590-1-e@80x24.org> (raw)
->cat_async and ->check_async may trigger each other (in future
callers) while waiting, so we need a unified method to ensure
both complete. This doesn't affect current code, but allows us
to slightly simplify existing callers.
