If anyone has any objections, please let me know. ------------------ From: Johannes Berg commit 7b4ec8dd7d4ac467e9eee4d49f2c9574d773efbb upstream. sparse complains about any __ksymtab symbols with the following: warning: symbol '__ksymtab_...' was not declared. Should it be static? due to Andi's patch making it non-static. Mollify sparse by declaring the symbol extern, otherwise we get drowned in sparse warnings for anything that uses EXPORT_SYMBOL in the sources, making it easy to miss real warnings.
