Subject: [Qemu-devel] [PATCH 1/4] exec: simplify phys_page_find() params
Date: Mon, 15 May 2017 16:50:57 +0800 [thread overview]
Message-ID: <1494838260-30439-2-git-send-email-peterx@redhat.com> (raw)
In-Reply-To: <1494838260-30439-1-git-send-email-peterx@redhat.com>
It really only plays with the dispatchers, so the parameter list does
not need that complexity. This helps for readability at least.
