From f5fe81daea622f8f043edc19fb61ba367b6958aa Mon Sep 17 00:00:00 2001 From: =?utf8?q?Michel=20D=C3=A4nzer?= Date: Thu, 26 Apr 2012 11:44:11 +0200 Subject: [PATCH] gallium/radeon: Fix losing holes when allocating virtual address space. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If a hole exactly matches the allocated size plus alignment, we would fail to preserve the alignment as a hole. This would result in never being able to use the alignment area for an allocation again.
