Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII X-Net-Direct-Inc-MailScanner-Information: Please contact the ISP for more information X-Net-Direct-Inc-MailScanner: Found to be clean X-Net-Direct-Inc-MailScanner-SpamCheck: not spam, SpamAssassin (not cached, score=-36.8, required 5, autolearn=not spam, ALL_TRUSTED -1.80, BAYES_00 -15.00, INIT_RECVD_OUR_AUTH -20.00) X-Net-Direct-Inc-MailScanner-From: rpjday@mindspring.com Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org just curious -- under kernel hacking, there is the option UNUSED_SYMBOLS to "Enable unused/obsolete exported symbols" using EXPORT_UNUSED_SYMBOL[_GPL]. reads the help text (in part): "This option is provided temporarily to provide a transition period in case some external kernel module needs one of these symbols anyway." but it's not clear if that means that it was a *one-time* transition aid which is now unnecessary, or whether it's an *ongoing* aid which might be used at any time. currently, there are no invocations of EXPORT_UNUSED_SYMBOL[_GPL] anywhere in the tree. so does that mean this feature can be tossed? or might it still be used every so often? rday -- ======================================================================== Robert P.
