From 927ba12b53c90ebd8a2c4e3806d1052e7d604ded Mon Sep 17 00:00:00 2001 From: Rafael Antognolli Date: Fri, 7 Dec 2018 16:46:37 -0800 Subject: anv/tests: Adding test for the state_pool padding. Add a test that checks that we can use the extra space allocated for padding while allocating larger anv_states.
