(there are exceptions to this, but if you need them you should ask yourself if you really really want bitfields in that case) I'm not sure it matters much, but I suspect that as long as your fields aren't bigger than 32 bits, you should go for "unsigned int". This gives the compiler more freedom to deal with them... -- Kernelnewbies: Help each other learn about the Linux kernel.
