Can we hold a spin lock and call up() (on a semaphore)

Hi:

In process context (and interrupt context, while we are at it) can we
hold a spin lock and call up() (on a semaphore)? Apart from the usual
issues pertaining with deadlocks - are we guaranteed that an up is a
non-blocking operation?

Thanks,

Hareesh
