AFAIK, the ACL administration code doesn't hook into the VFS layer,
although I know several people who think that would be a cool feature
;)

To see how ACL modification works, look at src/venus/fs.c, and
src/afs/afs_pioctl.c.  Probably the best solution would be to write a
new variant of afs_HandlePioctl that doesn't copyin and copyout the
pioctl args, and then write a kernelspace implementation of the ACL
serialization code from fs.c.
