Subject: [PATCH 32/38] httpd/async: describe which ->write subs it can call
Date: Sat, 10 Sep 2022 08:17:23 +0000	[thread overview]
Message-ID: <20220910081729.2011934-33-e@80x24.org> (raw)
In-Reply-To: <20220910081729.2011934-1-e@80x24.org>

I initially wanted to rename GzipFilter->write to
GzipFilter->writev to reflect the multi-argument nature of the
sub, and it wasn't worth the memory to maintain an alias.
