system faulting in pages if it does e.g. fragment reallocation * get rid of rumpvm_findpage() and always use uvm_pagelookup() * determine a vnode's cleanness by flagging it as being on the work list if we "take" a write fault and removing it from the worklist once pages are flushed. There is no work list here, but at least there is symmetry with the kernel.
