Introduce seperate queues for operations that do not modify the semaphore values. Advantages: - Simpler logic in check_restart(). - Faster update_queue(): Right now, all wait-for-zero operations are always tested, even if the semaphore value is not 0. - wait-for-zero gets again priority, as in linux <=3.0.9
Whether this complexity is wanted is not for me to decide, as I am not the ipc/sem.c maintainer. I'll leave that up to Andrew and Linus. The code looks correct, though.
