Subject: [PATCH 29/56] migration: Move migrate_use_xbzrle() to options.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
RH-Author: Peter Xu <peterx@redhat.com>
RH-MergeRequest: 162: migration: Pretty failures for postcopy on unsupported memory types
RH-Bugzilla: 2057267
RH-Acked-by: Leonardo Brás <leobras@redhat.com>
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
RH-Acked-by: quintela1 <quintela@redhat.com>
RH-Commit: [28/50] fc8bee0f691a96e6bd0b41f2511abe507b81fea5 (peterx/qemu-kvm)
Once that we are there, we rename the function to migrate_xbzrle()
to be consistent with all other capabilities.
We change the type to return bool also for consistency.
