* - Introduce the Hhook (Helper Hook) KPI. The KPI is closely modelled on pfil(9),lstewart2010-12-211-0/+457
and in many respects can be thought of as a more generic superset of pfil. Hhook provides a way for kernel subsystems to export hook points that Khelp modules can hook to provide enhanced or new functionality to the kernel. The KPI has been designed to ensure hook points pose no noticeable overhead when no hook functions are registered. - Introduce the Khelp (Kernel Helpers) KPI. Khelp provides a framework for managing Khelp modules, which indirectly use the Hhook KPI to register their hook functions with hook points of interest within the kernel. Khelp modules aim to provide a structured way to dynamically extend the kernel at runtime in an ABI preserving manner. Depending on the subsystem providing hook points, a Khelp module may be able to associate per-object data for maintaining relevant state between hook calls. - pjd's Object Specific Data (OSD) KPI is used to manage the per-object data allocated to Khelp modules. Create a new "OSD_KHELP" OSD type for use by the Khelp framework. - Bump __FreeBSD_version to 900028 to mark the introduction of the new KPIs.
