[Qemu-devel] [PATCH V3 0/2] Implement sync modes for drive-backup.

[Ian Main]

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.
  Add tests for sync modes 'TOP' and 'NONE'
