Will you be bringing these fixes into 5.7?  The main fix is the 2nd patch, =
but
there wasn't a clear "Fixes:" tag to add because the problem is due more to
how Hyper-V operates than a bug in a previous Linux commit.  We have a
customer experiencing the problem, so getting the fix into the main tree
sooner rather than later is helpful.

Thx,

Michael
