Hi! I'm working on the usb mass storage support for linux. For this, we
have a kernel thread which blocks on a semaphore (used to indicate the
number of commands in the queue).

The problem is, when I block on the semaphore, the process is still marked
as runnable, and thus drives the load average up to 1.00. How do I sleep
so that I don't drive up the load? Or how do I mark the process as
sleeping on a semaphore for the purposes of load average calculation?
