Aaah. Thanks.

Yes, will do, thanks.
And note that one of the reasons for this patch was to make
wait_event_interruptible() and __wait_event_interruptible()
interchangeable, like wait_event() and __wait_event().
irda_getsockopt() uses __wait* exactly because it has already
checked the condition.
Samuel, will you agree with the patch below?
Yes, this adds the unnecessary check. We will remove it later,
after we change wait_event* macros, just
- err = wait_event_interruptible(...);
+ err = __wait_event_interruptible(...);
Otherwise, this patch should also change af_irda.c (and probably
other callers), not good.
Oleg.
