From a100d88df1e924e5c9678fabf054d1bae7ab74fb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Radim=20Kr=C4=8Dm=C3=A1=C5=99?= Date: Tue, 27 May 2014 19:16:20 +0200 Subject: hv: use correct order when freeing monitor_pages MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We try to free two pages when only one has been allocated. Cleanup path is unlikely, so I haven't found any trace that would fit, but I hope that free_pages_prepare() does catch it.
