- * FIXME: write proper description
+ * This function is invoked when there's space available in the socket's

+ * clears the SOCK_NOSPACE flag indicating that memory for writing
+ * is now available, wakes up any processes waiting for write operations
+ * and sends asynchronous notifications if needed.
