-/*
- * l_wait_event is a flexible sleeping function, permitting simple caller
- * configuration of interrupt and timeout sensitivity along with actions to
- * be performed in the event of either exception.
- *
- * Common usage looks like this:
- *
- * struct l_wait_info lwi = LWI_TIMEOUT_INTR(timeout, timeout_handler,
- * intr_handler, callback_data);
- * rc = l_wait_event(waitq, condition, &lwi);
- *
- * (LWI_TIMEOUT and LWI_INTR macros are available for timeout- and
- * interrupt-only variants, respectively.)
- *
- * If a timeout is specified, the timeout_handler will be invoked in the event
- * that the timeout expires before the process is awakened. (Note that any
- * waking of the process will restart the timeout, even if the condition is
- * not satisfied and the process immediately returns to sleep. This might be
- * considered a bug.) If the timeout_handler returns non-zero, l_wait_event
- * will return -ETIMEDOUT and the caller will continue. If the handler returns
- * zero instead, the process will go back to sleep until it is awakened by the
- * waitq or some similar mechanism, or an interrupt occurs (if the caller has
- * asked for interrupts to be detected). The timeout will only fire once, so
- * callers should take care that a timeout_handler which returns zero will take
- * future steps to awaken the process. N.B. that these steps must include
- * making the provided condition become true.
- *
- * If the interrupt flag (lwi_signals) is non-zero, then the process will be
- * interruptible, and will be awakened by any "killable" signal (SIGTERM,
- * SIGKILL or SIGINT). If a timeout is also specified, then the process will
- * only become interruptible _after_ the timeout has expired, though it can be
- * awakened by a signal that was delivered before the timeout and is still
- * pending when the timeout expires. If a timeout is not specified, the process
- * will be interruptible at all times during l_wait_event.
