[Qemu-devel] [PATCH V3 0/4] qapi and snapshot code clean up in block layer

[Wenchao Xia <xiawenc@linux.vnet.ibm.com>]

These patches are the common part of my hmp/qmp block query series and Pavel's
qmp snapshot command converion series. It mainly does following things:
1 move snapshot related code to block/snapshot.c, qmp and info dumping code to
block/qapi.c.
2 better info dumping function to get rid of buffer, avoid string truncation.

v2:
  Squash code moving patches since they are reviewed in v1.
  Drop bdrv_snapshot_find() function change patch, since it related to snapshot
logic which should be changed together with Pavel's serial.
  Use a parameter in message_printf() to tell where to print, instead of use
global variable "cur_mon" inside.

v3:
  Address Stefan's comments:
  2/4: do not move bdrv_is_snapshot().
  4/4: reuse fprintf_function function pointer instead of a new function.

Stefan Hajnoczi (1):
  1 block: drop bs_snapshots global variable

Wenchao Xia (3):

  3 block: move qmp and info dump related code to block/qapi.c
  4 block: dump snapshot and image info to specified output
