Subject: [PATCH 02/25] child: fix usage of gzFile and gzopen()
Date: Wed,  9 Feb 2022 14:25:47 -0800	[thread overview]
Message-ID: <20220209222610.438470-3-mcgrof@kernel.org> (raw)
In-Reply-To: <20220209222610.438470-1-mcgrof@kernel.org>

The code uses gzFile as a pointer, but it is not the
intended design. This works as a pointer works just
as well as the stupid file descriptor. Fix this usage
to shut up gcc compilation warnings and make proper use
of the API.
