[Qemu-devel] [PATCH v4 0/4] fsdev: qmp interface for io throttling

[Pradeep Jagadeesh]

These patches provide the qmp interface, to query the io throttle 
status of the all fsdev devices that are present in a vm.
also, it provides an interface to set the io throttle parameters of a
fsdev to a required value. some of the patches also remove the duplicate
code that was present in block and fsdev files. 

Pradeep Jagadeesh (4):
  throttle: factor out duplicate code
  qmp: Create IOThrottle structure
  qmp: refactor duplicate code
  fsdev: QMP interface for throttling
