Andy, thanks for taking these.  All these changes passed our tests
except for TRIM.

It looks like we'll need to take a closer look at how to fix TRIM
upstream.  We probably will not get that upstream before kernel freeze.
Do you think it be possible to re-base your original patch to re-enable
SPC-3 in Hyper-V so that we don't regress this feature
(http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-
trusty.git;a=commit;h=ff2c5fa3fa9adf0b919b9425e71a8ba044c31a7d)?
