Hmm, I pulled this and then did an allmodconfig build. I expected that to be a full rebuild, since the plugins got recompiled, but it turned out to just take 16 seconds because it only compiled the plugins, not any of the object files. I'm doing a _proper_ full build with this after doing a git clean -dqfx to actually clean everything out, but it did make me go "Umm". Maybe we don't care. I guess the plugins are all supposed to be stable in the sense that any updates don't change the generated code. But it does strike me as a honking big hole for verification of plugin changes. So I don't think this necessarily requires any changes to our Kbuild infrastructure, but I thought I'd mention it since this clearly didn't match my naive expectations. Linus
