Based on the note that "This code path is not used post Linux 4.1", Xenial 16.04 and newer releases should not be impacted. This would only need to be considered for the v3.13 based Trusty 14.04 kernel. Will fix up the nominations accordingly. Thanks.

If there are gaps, data is copied to a bounce buffer and a continuous data buffer is passed to Hyper-V. The check on gaps assumes SG list is continuous, and not chained. This is not always true. Failing the check may result in incorrect I/O data passed to the Hyper-v device. This code path is not used post Linux 4.1.
