From 455e861cc625891baacf74e66c31a914883b80ca Mon Sep 17 00:00:00 2001 From: John Snow Date: Fri, 22 May 2015 14:13:42 -0400 Subject: [PATCH] libqos/ahci: Fix sector set method || probably does not mean the same thing as |. Additionally, allow users to submit a prd_size of 0 to indicate that they'd like to continue using the default.
