PF.H

The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the PF.H header at

d:\th\minkernel\ntos\inc

and draws from it the following type definitions:

Line Number Type
70 struct _PF_KERNEL_GLOBALS
413 enum _PF_FILE_ACCESS_TYPE

The header PF.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).
