From 98fda169290b3b28c0f2db2b8f02290c13da50ef Mon Sep 17 00:00:00 2001 From: =?utf8?q?Radim=20Kr=C4=8Dm=C3=A1=C5=99?= Date: Wed, 4 Sep 2013 22:32:24 +0200 Subject: [PATCH] kvm: remove .done from struct kvm_async_pf MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit '.done' is used to mark the completion of 'async_pf_execute()', but 'cancel_work_sync()' returns true when the work was canceled, so we use it instead.
