Hi Rich,

I'm pretty sure I know the cause of that problem -- the current knfsd
isn't obeying all of the vfs locking protocols. Under some circumstances
it may check for existence, find the file doesn't exist, and then go to
create the file and find that it's already been created (that's the
"dentry not negative!" part.)

Guess I need to find some round tuits and get this fixed ...

Regards,
Bill
