Subject: [PATCH v2 0/3] hv: vmbus: add fuzz testing to hv device

This patchset introduces a testing framework for Hyper-V drivers.
This framework allows us to introduce delays in the packet receive
path on a per-device basis. While the current code only supports
introducing arbitrary delays in the host/guest communication path,
we intend to expand this to support error injection in the future.

Changes in v2:
  Patch 1: As per Vitaly's suggestion, wrapped the test code under an
           #ifdef and updated the Kconfig file, so that the test code
           will only be used when the config option is set to true.
           (default is false).

           Updated hyperv_vmbus header to contain new #ifdef with new
           new functions for the test code.

  Patch 2: Moved code from under sysfs to debugfs and wrapped it under
           the new ifdef.

           Updated MAINTAINERS file with new debugfs-hyperv file under
           the section for hyperv.

  Patch 3: Updated testing tool with new debugfs location.

Branden Bonaby (3):
  drivers: hv: vmbus: Introduce latency testing
  drivers: hv: vmbus: add fuzz test attributes to debugfs
  tools: hv: add vmbus testing tool
