From 698d0f377d72fdc8d4e247e76b6508090c366187 Mon Sep 17 00:00:00 2001 From: Razvan Cojocaru Date: Mon, 5 Sep 2016 12:47:46 +0200 Subject: [PATCH] have __DEFINE_COMPAT_HANDLE() generate const versions Both DEFINE_XEN_GUEST_HANDLE() and __DEFINE_XEN_GUEST_HANDLE() each produce both const and non-const handles, only DEFINE_COMPAT_HANDLE() does (__DEFINE_COMPAT_HANDLE() does not). This patch has __DEFINE_COMPAT_HANDLE() also produce a const handle.
