[Qemu-devel] [PATCH v6 0/6] 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 (6):
  throttle: factor out duplicate code
  qmp: Create IOThrottle structure
  throttle: move out function to reuse the code
  hmp: create a throttle initialization function for code reusability
  fsdev: hmp interface for throttling
  fsdev: QMP interface for throttling

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 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:
 Addresssed 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.

v3 -> v4:
 Addressed comments from Eric Blake and Greg Kurz
 Re-ordered the patches
 Added the dummy functions in qmp.c to address the cross compilation issues

v4 -> v5:
  Addressed comments from Eric Blake and Greg Kurz
  Split the fsdev qmp patch into hmp and qmp related patches
  Moved the common functionalities to throttle.c instead of creating
  a new file

v5 -> v6:
  Addressed comments from Greg Kurz and Markus Armbruster
  Split the commits to specific to hmp and throttle as suggested by Greg
  Moved ThrottleConfig typedef to qemu/typedefs.h
