Hi,

I was looking at the sources to kenfs and saw something that confused me -

ilock() (pc/lock.c) calls splhi() and then calls lock(). If that lock were contended,
how would the system not stop? And on a UP system, if you're inside an splhi() block,
why would you need to take an uncontended lock?

Thanks,
