Subject: [PATCH 15/38] view: reduce subroutine calls for submsg_hdr
Date: Sat, 10 Sep 2022 08:17:06 +0000	[thread overview]
Message-ID: <20220910081729.2011934-16-e@80x24.org> (raw)
In-Reply-To: <20220910081729.2011934-1-e@80x24.org>

Favor fewer, yet more expensive operations than many smaller
ones.  While we're still directly manipulating ctx->{obuf} after
this, this change makes it easier for us to avoid doing so in
the future.
