1. the lio_sigsetup() method use a universal sighand instance across all aiocb instances, but inside the lio_sighandler() method, if one aiocb is handle finished, then this method will free the sighand instance that come along with current aiocb instance. thus when handle next aiocb instance, use-after-free crash will happen. in order to solve this problem, we make each aiocb instance have their own sighand instance 2. make the lio_listio implementation can pass the ltp/open_posix_testsuite/lio_listio testcases 3. the modification are referred to https://pubs.opengroup.org/onlinepubs/9699919799/functions/lio_listio.html Signed-off-by: guoshichao <guoshichao@xiaomi.com>
