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 (5):
throttle: factor out duplicate code
qmp: Create IOThrottle structure
qmp: refactor duplicate code
fsdev: hmp interface for throttling
fsdev: QMP interface for throttling
