	Hi Peoples,

	I am new to this partitucalar maillist. So if I break protocol or 
sound stupid please be patient with me.

	I am trying to make some testing changes to the NetBSD kernel on 
my machine. I am running NetBSD on my Amiga 3000. But these changes are 
for the most part, what I would consider, generic source code changes. 
I.e. they aren't in the amiga source directories but in the /sys/kern one.

	What I want to do is allocate a buffer in memory in the "user 
space" rather than in kernel space. And then use it to fake a syscall to 
kernel routine. i.e. I need this memory buffer to be accessible via the 
copyin and copyout commands.

	Actually I guess bottom line what I want to do is to be able to 
call the open and close file routines at the syscall entry level from 
inside the kernel.

	Does anyone know how? Can anyone provide me with some help and 
most especailly some answers. I am totally stumped at the moment, and 
everything I try just leads to kernel failures. 

	So basically any information would be greatly appriciated.

	Thanks A Million,
