- * eventfd_signal - Adds @n to the eventfd counter.

* @ctx: [in] Pointer to the eventfd context.
- * @n: [in] Value of the counter to be added to the eventfd internal counter.
- * The value cannot be negative.
*
* This function is supposed to be called by the kernel in paths that do not
* allow sleeping. In this function we allow the counter to reach the ULLONG_MAX
* value, and we signal this as overflow condition by returning a EPOLLERR
* to poll(2).
*
- * Returns the amount by which the counter was incremented. This will be less
- * than @n if the counter has overflowed.
