    From the changelog for the patch which added these functions:



    Adds 3 new completion API calls, which are a straightforward extension of
    the current APIs:

    int wait_for_completion_interruptible(struct completion *x);
    unsigned long wait_for_completion_timeout(struct completion *x,
    unsigned long timeout);
    unsigned long wait_for_completion_interruptible_timeout(
    struct completion *x, unsigned long timeout);

    This enables the conversion of more semaphore-using code to completions.
    There is code that cannot be converted right now (and is forced to use
    semaphores) because these primitives are missing. Thomas Gleixner has a
    bunch of patches to make use of them.
