[Qemu-devel] [PATCH for-1.6 0/4] Leaky bucket throttling and features

["Benoît Canet" <benoit@irqsave.net>]

The first patch fixes the throttling which was broken by a previous commit.

The next patch replace the existing throttling algorithm by the well described
leaky bucket algorithm.

Third patch implement bursting by adding *_threshold parameters to
qmp_block_set_io_throttle.

The last one allow to define the max size of an io when throttling by iops via
iops_sector_count to avoid vm users cheating on the iops limit.

Benoît Canet (4):
  block: Repair the throttling code.
  block: Modify the throttling code to implement the leaky bucket
    algorithm.
  block: Add support for throttling burst threshold in QMP and the
    command line.
  block: Add iops_sector_count to do the iops accounting for a given io
    size.
