Subject: [Qemu-devel] [PATCH 12/22] ram: save_live_setup() we don't need to synchronize the dirty bitmap.
Date: Fri, 13 Jul 2012 09:23:34 +0200	[thread overview]
Message-ID: <1342164224-32709-13-git-send-email-quintela@redhat.com> (raw)
In-Reply-To: <1342164224-32709-1-git-send-email-quintela@redhat.com>

1st: we were synchonizing the dirty bitmap before calling
      memory_global_dirty_log_start().

2nd: We are marking all pages as dirty anywhere, no reason to go
     through all the bitmap to "mark" dirty same pages twice.

So, call removed.
