Can't be, it wouldn't be all of anything-init if there are calls back into it.

For hotplugs you'd just call (and load) foo-init again, if it's a module. It can be a module even though foo-driver is part of the kernel, why not? It's just that I don't see this as very relevant. My kernels weigh in at something like 1Mb uncompressed, and unload just 36K of init stuff, i.e., some 3-4%. If you invest a few pages in the kernel to manage all this, you loose overall. -- Dr. Horst H. von Brand mailto:vonbrand@inf.utfsm.cl Departamento de Informatica Fono: +56 32 654431 Universidad Tecnica Federico Santa Maria +56 32 654239 Casilla 110-V, Valparaiso, Chile Fax: +56 32 797513
