I think turning JIT off is a valid use case, the rest looks much more iffy. I am not sure we want to let people tell the engine to JIT certain functions - are there a lot of cases where the engine wouldn't do it but it's actually the right thing to do? Don't see any use for "opcache.jit=attributes". -- Stas Malyshev smalyshev@gmail.com
