[Qemu-devel] [PATCH 0/6] block: bdrv_load/save_vmstate() cleanups

From: Kevin Wolf
Subject: [Qemu-devel] [PATCH 0/6] block: bdrv_load/save_vmstate() cleanups
Date: Fri, 10 Jun 2016 18:05:16 +0200

This series contains a few cleanups with respect to the vmstate I/O functions.
Apart from making the interface more consistent (writes were already vectored,
but not reads), this makes use of the new byte-based .bdrv_co_preadv/pwritev
callbacks in qcow2 to get rid of a few hacks, including bs->zero_beyond_eof.

Kevin Wolf (6):
  block: Introduce bdrv_preadv()
  block: Make .bdrv_load_vmstate() vectored
  block: Allow .bdrv_load/save_vmstate() to return 0/-errno
  block: Make bdrv_load/save_vmstate coroutine_fns
  qcow2: Let vmstate call qcow2_co_preadv/pwrite directly
  block: Remove bs->zero_beyond_eof
