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 Makefile | 3 + blockdev.c | 97 ++------------------------------- fsdev/qemu-fsdev-dummy.c | 10 ++++ fsdev/qemu-fsdev-throttle.c | 118 ++++++++++++++++++++++++++-------------- fsdev/qemu-fsdev-throttle.h | 13 +++++ fsdev/qemu-fsdev.c | 37 +++++++++++++ hmp-commands-info.hx | 18 ++++++ hmp-commands.hx | 19 +++++++ hmp.c | 87 +++++++++++++++++++++++++++-- hmp.h | 4 ++ include/qemu/throttle-options.h | 7 +++ monitor.c | 5 ++ qapi-schema.json | 3 + qapi/block-core.json | 76 +------------------------- qapi/fsdev.json | 84 ++++++++++++++++++++++++++++ qapi/iothrottle.json | 88 ++++++++++++++++++++++++++++++ qmp.c | 15 +++++ util/throttle.c | 110 +++++++++++++++++++++++++++++++++++++ 18 files changed, 580 insertions(+), 214 deletions(-) create mode 100644 qapi/fsdev.json create mode 100644 qapi/iothrottle.json 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 -- 1.8.3.1
