[Qemu-devel] [PATCH V2 0/5] block: make qmp_transaction extendable

[Wenchao Xia]

  This serial will package backing chain snapshot code as one case, to make it
possible adding more operations later.

v2:
  Address Kevin's comments:
  Use the same prototype prepare, commit, rollback model in original code,
commit should never fail.

Wenchao Xia (5):
  block: package preparation code in qmp_transaction()
  block: move input parsing code in qmp_transaction()
  block: package committing code in qmp_transaction()
  block: package rolling back code in qmp_transaction()
  block: make all steps in qmp_transaction() as callback
