Ok, so near as I can tell, the do_vserver syscall handler takes
the immutable, barrier, and iunlink flag values and sticks them
into the inode->i_attr_flags. It then calls setattr(), in which
vserver stores these values into the inode->i_flags. That is
then where the flags are enforced.

So I'll whip up a new patch wherein do_vserver() sets inode->i_flags
directly. Do we expect that to work, or am I misunderstanding the
existing logic?
