sir! There is no problem in compiling with Makefile.But, as i 've mentioned in my last mail, i want to understand the "/usr/src/linux/kernel/sched.c' .I want to play with it's parameters and will try to include a pointer such that i can calculate waiting time for process in the waiting queue(as, i guess this is n't already implemented. if it is please give me some idea.) . For this purpose i want to know that what vlaues of differnet MACRO has been used by the sched.c . so; please send me information about it. Abhijit ( i 'm sending this mail to fedora list because i think perhaps i 've missed some points in my previous mail.)
