From d7531638db73396c9e89ade086bbeab6023656f9 Mon Sep 17 00:00:00 2001 From: John Snow Date: Thu, 17 Sep 2015 14:17:04 -0400 Subject: [PATCH] qtest/ahci: use generate_pattern everywhere Fix the pattern generation to actually be interesting, and make sure all buffers in the ahci-test actually use it.
