hi, On linux, I found the scheduling policies are defined as follow:
in /usr/include/bits/sched.h /* Scheduling algorithms. */ #define SCHED_OTHER 0 #define SCHED_FIFO 1 #define SCHED_RR 2 #ifdef __USE_GNU # define SCHED_BATCH 3 # define SCHED_IDLE 5 # define SCHED_RESET_ON_FORK 0x40000000 #endif So besides SCHED_OTHER, SCHED_FIFO and SCHED_RR, there are another two policies, SCHED_BATCH and SCHED_IDLE. And 3 is a valid value for the scheduling policy, which causes the test returns UNSOLVED on linux system. Here is the patch, please comment!
