Actually, I think you only need disable_intr && restore_intr, which should be paired over tight MD code sections, and yes, leaving it ambigious is desirable IMO. .\" -*- nroff -*- .\" .\" Copyright (c) 2001 Farley Karbunkle .\" .\" All rights reserved. .\" .\" This program is free software. .\" .\" Redistribution and use in source and binary forms, with or without .\" modification, are permitted provided that the following conditions .\" are met: .\" 1.
