[Qemu-devel] [PATCH v3 0/6] block: remove legacy I/O throttling

[Manos Pitsidianakis <el13635@mail.ntua.gr>]

This series depends on my other series 'add throttle block driver filter'
currently on v9

Based-on: <20170825132028.6184-1-el13635@mail.ntua.gr>

Replacing the current I/O interface means the user will use the same options as
before and QEMU will create a hidden throttle filter node beneath the device's
BlockBackend. 

v3:
  fix suggestions by berto
  new commit: remove throttle-groups list

v2:
  new commit: require job-id when device is a node name
  new commit: remove BlockBackendPublic
  new commit: add dedicated iotest
  cleanup reference counting in block/block-backend.c functions
  add new function to get filter child bs
  take ownership of options in bdrv_new_open_driver()

Manos Pitsidianakis (7):
  block: skip implicit nodes in snapshots, blockjobs
  block: add options parameter to bdrv_new_open_driver()
  block: require job-id when device is a node name
  block: remove legacy I/O throttling
  block/throttle-groups.c: remove throttle-groups list
  block: remove BlockBackendPublic
  qemu-iotests: add 191 for legacy throttling interface
