/* * uvm_km_pgremove_intrsafe: like uvm_km_pgremove(), but for non object backed * regions. * * => when you unmap a part of anonymous kernel memory you want to toss * the pages right away. (this is called from uvm_unmap_...). * => none of the pages will ever be busy, and none of them will ever * be on the active or inactive queues (because they have no object). */
