In most of the cases, a static symbol marked for # exporting is an odd combination that should be fixed either by deleting # the exporting mark or by removing the static attribute and adding the # appropriate declaration to headers. # # This check could help to detect the following problems: # 1. 550113d4e9f5 ("i2c: add newly exported functions to the header, too") # 2. 54638c6eaf44 ("net: phy: make exported variables non-static") # 3. 98ef2046f28b ("mm: remove the exporting of totalram_pages") # 4. 73df167c819e ("s390/zcrypt: remove the exporting of ap_query_configuration") # 5. a57caf8c527f ("sunrpc/cache: remove the exporting of cache_seq_next") # 6. e4e4730698c9 ("crypto: skcipher - remove the exporting of skcipher_walk_next") # 7. 14b4c48bb1ce ("gve: Remove the exporting
