Sorry, I think that should be:
static inline int down_timeout(struct semaphore
There has been some discussion on lkml about a function that would
either down a semaphore or else abort if it couldn't get the semaphore
in a certain amount of time. Something along the lines of:
down_timeout(struct semaphore *sem, long timeout);
Does something like this exist?

It seems like we need to implement down_timeout (and
down_timeout_interruptible) to fully flesh out the semaphore implementation.
It is difficult and inefficient to emulate this using wrapper functions, as
far as I can see.
Seems like this is a fairly standard interface to have for OS semaphores
