This patch adds sync modes on top of the work that Stefan Hajnoczi has done.
These patches apply on kevin/block with '[PATCH] block: add drive_backup HMP command' also applied. Hopefully all is in order as this is my first QEMU patch. Many thanks to Stephan and Fam Zheng for their help. V2: - No longer poll, instead use qemu_coroutine_yield(). - Use bdrv_co_is_allocated(). - Much better SYNC_MODE_NONE test. V3: - A few style fixes. - Better commit message explaining how TOP and NONE operate. - Verified using checkpatch.pl. Ian Main (2): Implement sync modes for drive-backup.
