o Add a comment to exec_check_permissions() to indicate that the
passed vnode must be locked; this is the case because of calls
to VOP_GETATTR(), VOP_ACCESS(), and VOP_OPEN(). This becomes
more of an issue when VOP_ACCESS() gets a bit more complicated,
which it does when you introduce ACL, Capability, and MAC
support.
