      livepatch: introduce shadow variable API · 439e7271
      Joe Lawrence authored
      
      
      Add exported API for livepatch modules:
      
        klp_shadow_get()
        klp_shadow_alloc()
        klp_shadow_get_or_alloc()
        klp_shadow_free()
        klp_shadow_free_all()
      
      that implement "shadow" variables, which allow callers to associate new
      shadow fields to existing data structures.  This is intended to be used
      by livepatch modules seeking to emulate additions to data structure
      definitions.
      
      See Documentation/livepatch/shadow-vars.txt for a summary of the new
      shadow variable API, including a few common use cases.
      
      See samples/livepatch/livepatch-shadow-* for example modules that
      demonstrate shadow variables.
