In particular, sparse complains as follows: SP test-string-list.c test-string-list.c:10:6: warning: symbol 'parse_string_list' was not \ declared. Should it be static? test-string-list.c:18:6: warning: symbol 'write_list' was not \ declared. Should it be static? test-string-list.c:25:6: warning: symbol 'write_list_compact' was not \ declared. Should it be static? test-string-list.c:38:5: warning: symbol 'prefix_cb' was not \ declared. Should it be static? In order to suppress the warnings, since the above symbols do not need more than file scope, we simply include the static modifier in their declaration.
