- * sysdeps/pthread/aio_suspend.c (aio_suspend): Set errno to EINTR
- if this is what pthread_cond_wait returned.
+ * sysdeps/pthread/aio_misc.h: Mark __aio_requests_mutex,
+ __aio_enqueue_request, __aio_find_req, __aio_find_req_fd,
+ __aio_free_request, __aio_notify, and __aio_sigqueue as hidden.
+
+ * sysdeps/pthread/aio_suspend.c (aio_suspend): Set errno to the result
+ of pthread_cond_wait if there was an error. Use pthread_cleanup_*
+ instead of __lbic_cleanup_region_*.
