Hello! We are working on a linux kernel module on AMD64 and are using ktime.h. Now we want to use ktime_to_timeval, which is defined over a macro for ns_to_timeval on 64bit cpus, to transform a ktime_t struct to a struct timeval (see http://lxr.linux.no/source/include/linux/ktime.h#L111 for the definition of ns_to_timeval). But the compiler says "ns_to_timeval" is undefinded as a warning. Now this should not be a problem because I've read it will be resolved when the module is loaded. But here comes the problem, it is not resolved and the module not loaded. Any idea why? Do I have to enable some kernel time option and recompile the kernel? Kernel is 2.6.18.2, we are developing in User Mode Linux. Best regards, Helmut -- Kernelnewbies: Help each other learn about the Linux kernel.
