[SRU][Precise][PATCH 0/1] hv: do not lose pending heartbeat vmbus packets

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1632786

== SRU Justification ==
Hyper-V hosts can continue sending heartbeat packets to guests independent
of whether earlier packets have responses, which led to a potential issue
of these packets being dropped when responses took too long to process.
Lost heartbeats will lead to the host diagnosing that the guest is dead and 
should be shut down and restarted.

Commit 407a3aee6ee2 fixes this bug and has landed in mainline as of
v4.9-rc3.  It has also been cc'd to stable.

All Ubuntu stable releases required this patch.  However, Precise has
a difference context diff, so that is why it is being SRU'd separatly.

    hv: do not lose pending heartbeat vmbus packets


== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
