Subject: [PATCH 07/12] linux-user: Replace bprm->fd with bprm->src.fd
Date: Fri, 18 Jun 2021 20:43:24 -0700	[thread overview]
Message-ID: <20210619034329.532318-8-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210619034329.532318-1-richard.henderson@linaro.org>

There are only a couple of uses of bprm->fd remaining.
Migrate to the other field.
