[Qemu-devel] [PATCH 1/4] exec: simplify phys_page_find() params


From: Peter Xu
Subject: [Qemu-devel] [PATCH 1/4] exec: simplify phys_page_find() params
Date: Mon, 15 May 2017 16:50:57 +0800

It really only plays with the dispatchers, so the parameter list does
not need that complexity. This helps for readability at least.
