<opinion from irrelevant person>
All of the patches look good to me except most of those which change
the handling of `rc=`. I have a personal style preference for
rc = -ENOMEM;
val = kalloc();
if (!val)
goto err;
vs
val = kalloc();
if (!val) {
rc = -ENOMEM;
goto err;
}
because it saves 1 line and I think the compiler does the right/same
thing. If there is preference among the people active in selinux
developers (like I said, I'm now irrelevant) I guess they win.
But certainly a big +1 from me for the array allocation and sizeof()
changes.
