Alan, The attached patch separates the notion of "maximum real-time priority" from what we actually export to user-space. This will also us, in the future, to have kernel threads with a greater RT priority than any user task. Right now the two values are set equal and thus the patch has no object code changes. It does provide a bit of a cleanup, however. Patch is against 2.4.19-pre7-ac4, please apply. Robert Love
