The dummy module is used by folk that run security conscious code(!?). A feature of such code (for example, dhclient) is that it tries to operate with minimum privilege (dropping unneeded capabilities). While the dummy module doesn't restrict code execution based on capability state, the user code expects the kernel to appear to support it. This patch adds back faked support for the PR_SET_KEEPCAPS etc., calls - making the kernel behave as before 2.6.26.
