From 9e029689e1228a218452d5c7b661ef208d22f71a Mon Sep 17 00:00:00 2001 From: Alberto Garcia Date: Thu, 15 Feb 2018 15:10:08 +0200 Subject: qcow2: Replace align_offset() with ROUND_UP() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The align_offset() function is equivalent to the ROUND_UP() macro so there's no need to use the former. The ROUND_UP() name is also a bit more explicit. This patch uses ROUND_UP() instead of the slower QEMU_ALIGN_UP() because align_offset() already requires that the second parameter is a power of two.
