You're missing the point here. Find something useful to change. People are going through the kernel finding functions that should be static for example - this is useful as it provides better documentation for those functions (static == not used outside this file) and fixes errors reported by GCC and static code checkers. Those changes are useful. Another useful change would be ensuring that every struct that has a bool member is kzalloc'd instead of kmalloc'd as this eliminates a possible source of undefined behaviour. (A bool is effectively a u8 with behaviour defined for when that value is 0 or 1, kmalloc'd memory can have any data in it, therefore it's possible and likely that a kmalloc'd struct with a bool member will end up with some value for that member that isn't 0 or 1. kzalloc eliminates this possibility.) Moving four assignments because you think they might improve stuff is just annoying people. >> He's not another Nick Krause. > > Are you going to remember me under an other nickname anyhow? Nick Krause submitted patches that make yours look good. At least yours compile. Thanks, -- Julian Calaby Email: julian.calaby@gmail.com Profile: http://www.google.com/profiles/julian.calaby/
