That's a coincedence, I remember seeing such a lab assignment
once

In /usr/src, for the filesystem fs/ in MINIX 2, servers/fs/ in
MINIX 3.

You'll also have to add calls to the library in lib/ and
include/minix/.

You'll get better answers if you ask more specific questions.

Good luck!

Ok I'll try again.
Yes, the source code for fili system in minix3 is /usr/src/servers/fs.
I want to implement Access Constrol Lists here, but my main problem is:
I dont know which file to edit. I want to know which file is in charge
of files, to be able put my list there..

Thanks.

There isn't a single file in FS that's in charge of files. The main
reference for a file is inode; its data structure is in inode.h. The
lookup of a name to inode is done by eat_path()/parse_path() in
path.c. open() happens in open.c.

In other words, can you be more specific ?
