[Qemu-devel] [PATCH v3 0/4] fsdev: qmp interface for io throttling

[Pradeep Jagadeesh <pradeepkiruvale@gmail.com>]

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

v0 -> v1:
 Addressed comments from Eric Blake, Greg Kurz and Daniel P.Berrange
 Mainly renaming the functions and removing the redundant code.

v1 -> v2:
 Addressed the comments from Eric Blake and Greg Kurz.
 As per the suggestion I split the patches into smaller patches.
 Removed some more duplicate code.

v2 -> v3:
 Addressed the comments from Alberto Garcia.
 Changed the comment from block to iothrottle in the iothrottle.json 
 Added the dummy functions in qemu-fsdev-dummy.c to address the compilation
 issues that were observed.
