Konstantin Belousov 6f2af3fcf3 Rework the handling of the tmpfs node backing swap object and tmpfs ... vnode v_object to avoid double-buffering. Use the same object both as the backing store for tmpfs node and as the v_object. Besides reducing memory use up to 2x times for situation of mapping files from tmpfs, it also makes tmpfs read and write operations copy twice bytes less. VM subsystem was already slightly adapted to tolerate OBJT_SWAP object as v_object. Now the vm_object_deallocate() is modified to not reinstantiate OBJ_ONEMAPPING flag and help the VFS to correctly handle VV_TEXT flag on the last dereference of the tmpfs backing object.
