Include one or the other depending on whether HYPERV_NONTLFS_HEADERS is defined. This will allow Hyper-V code to use the new headers while other code can continue using hyperv-tlfs.h which is only for Hyper-V guests. Replace hyperv-tlfs.h in shared headers with hv_defs.h These headers are shared between Hyper-V code and non-Hyper-V code (KVM for example). This will allow switching to the new headers in Hyper-V code only.
