Hi , I am planning to share data between my kernel driver (module) and a user program using shared memory. I am calling sys_shmget in the initialization function of the module.. when i insert the module it crybs for unresolved symbol sys_shmget. I have Virtual Memory file system support built in kernel(2.4.2) & compiled my module with the following options -DMODULE -D__KERNEL__ -O2 ... Am i missing some of the dependencies ?
