In schred.c? Do you mean include/linux/sched.h instead by any chance? Because that's the only place where INIT_TASK_SIZE is actually used. Why do you think you can't increase it? > Im running a heavy loaded RTLinux subsystem and the hole system (2.4.4 from Denx) go's down when I start a big program in Linux user-space. Um... you don;t want run RTL on a 8xx system; there are a couple of bugs which have never been fixed - and we (DENX) will not spend any further efforts on RTL. Use RTAI instead, which will continue to be supported on 8xx and other PPC systems.
