[Qemu-devel] [PATCH] qom: add helpers REGISTER_STATIC_TYPE[S]() |
Date: |
Tue, 3 Oct 2017 14:14:46 +0200 |
it will help to remove code duplication in places
that currently open code registration of static
type[s] and remove necessity to declare function
for type_init() to call, when only static types
need to be registered.

I'm going to use it for CPU types in followup patches
