And then later added in patch 7/7 – where SeLinux uses it? Data source support doesn't belong in this patch. Each patch should do one logical thing and only that one thing. This patch is adding support for measuring critical data. The data source patch will limit the critical data being measured. Other than updating the data source list in the documentation, definitely do not add data source support to the SELinux patch. thanks, Mimi
