| Subject: export: declare ksymtab symbols |
| |
| From: Johannes Berg <johannes.berg@intel.com> |
| |
| 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. |
| |
| Fixes: e0f244c63fc9 ("asmlinkage, module: Make ksymtab [...] __visible") |
