-Subject: [PATCH] bug: introduce ASSERT_STRUCT_OFFSET
-
-ASSERT_STRUCT_OFFSET allows to assert during the build of
-the kernel that a field in a struct have an expected offset.
-
-KVM used to have such macro, but there is almost nothing KVM specific
-in it so move it to build_bug.h, so that it can be used in other
-places in KVM.
