=======================
My module part with find the string with textsearch:
-------------------------------
int pos, err;
struct ts_config *conf;
struct ts_state state;
list_for_each_entry_safe(entry, next, &head, list) {
conf = textsearch_prepare("bm", entry->content,
strlen(entry->content), GFP_KERNEL, TS_AUTOLOAD);
if (IS_ERR(conf))
err = PTR_ERR(conf);
pos = textsearch_find_continuous(conf, &state,
sb->data, sb->len);
if (pos != -1)
printk("%s: Contet: %s match!\n", MODULE_NAME,
entry->content);
textsearch_destroy(conf);
}
