[Spice-devel] [PATCH qxl-wddm-dod 2/8] Mark all functions that should go to non paged sections

Frediano Ziglio fziglio at redhat.com
Wed Sep 28 13:55:41 UTC 2016


This make sure that these function goes into the non
paged section.
Also this change is much shorter than marking code if
can be paged as almost code can be paged.
It's also coherent with other source files.
