Julian Elischer a5296b05b4 Submitted by: Matt Dillon <dillon@freebsd.org> ... The old VN device broke in -4.x when the definition of B_PAGING changed. This patch fixes this plus implements additional capabilities. The new VN device can be backed by a file ( as per normal ), or it can be directly backed by swap. Due to dependencies in VM include files (on opt_xxx options) the new vn device cannot be a module yet. This will be fixed in a later commit.
