函数原型：void audit_log_d_path(struct audit_buffer *ab, const char *prefix, const struct path *path)

返回类型：void

参数：

类型参数名称
struct audit_buffer *ab
const char *prefix
const struct path *path
2024  如果prefix则写入审计信息
2028  pathname等于开辟内存
2029  如果非pathname则
2030  audit_log_string(ab, "<no_memory>")
2031  返回
2033  p等于d_path(path, pathname, # chars in a path name including nul + 11)
2034  如果是错误则
2036  audit_log_string(ab, "<too_long>")
2037  否则audit_log_untrustedstring - log a string that may contain random characters*@ab: audit_buffer*@string: string to be logged* Same as audit_log_n_untrustedstring(), except that strlen is used to* determine string length.
