The knfsd code uses the inode semaphore for a number of locking situations, and if there are cases where the semaphore
isn't being released, it could show up as "semaphore in use" when the inode is freed.

It would be very helpful to find a repeatable case of this so I can see what's going on. A messed up semaphore count
could result in hanging or stuck operations, so it's important to track this down.
