Message-ID: <20020522165320.GC18059@lanl.gov> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.3.28i X-Eric-Unconspiracy: There ought to be a conspiracy X-Editor: Vim, http://www.vim.org Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Ok, stupid question of the moment- I always read about the kernel compilation benchmarks people run on the ultra-snazzy new machines, but do people actually run the kernels thus generated? I have visions of a process being backgrounded to generate some files, and not completing before the one of the old files gets linked into the kernel (because not all files were listed as dependencies, for example). So are the kernel's current Makefiles really SMP safe -- can one really run multiple jobs when building Linux kernels? Any horror stories, or am I just paranoid?
