Subject: wait_for_completion_interruptible() changes
Hi Andi, Ingo,
Recently the return value of wait_for_completion_interruptible() in case of
succesful completion has changed:
- in 2.6.23, it returns 0 on completion,
- in current linux-2.6.git, it returns -1 on completion.
I.e. this breaks all code that checks for a non-zero return value instead
of explicitly comparing with -ERESTARTSYS.
I suspect this is caused by the recent completion refactoring?
With kind regards,
Geert Uytterhoeven
