Mmm, I think the simplest way is to just rebuild the kernel with the new RPC, and look at the generated prototype. > Serialized structs in byte arrays seem to be the only way to get this, That's what Mach seems to do for most things, see device_set_status & co, thread_set_state & co, etc. Samuel
Re: Should diskfs_file_update be called in every io_write?
What I'm afraid of with such change is that some applications have gotten used to be able to call write(), lseek(back), write(again at the same place), lseek(back), etc. and just get one disk write. We'd need figures with some real-world testcase to be sure we don't hurt usual workcases. Samuel
