Excuse me for the delay. yes this patch fixes an issue in the test case.
Thanks for pointing out.
Subrata
Can you kindly apply the patch pointed by Daniel to the getcpu test case
Thanks

Could you try to run the testcase with CPU affinity to CPU0?
x86_64:~/ltp-full-20081022/:[1]#
./testcases/kernel/syscalls/getcpu/getcpu01
getcpu01 1 FAIL : getcpu() Failed, errno=0:Success
x86_64:~/ltp-full-20081022/:[1]# taskset -c 0
./testcases/kernel/syscalls/getcpu/getcpu01
getcpu01 1 PASS : getcpu() returned proper cpuid:0, node id:0
Later one proofs the point that returning 0 of the getcpu() function is
expected. Running this on a SMP system it's less likely it's running on
CPU0 all the time ... so it fails randomly. Setting affinity to CPU0 lets
the
testcase pass since getcpu() will also return 0.
Maybe this helps on debugging - i have no access to Cell processors, but
this
should be Arch independent (expect i386).
It's really a trivial thing... just remove the return from the
get_schedcpu() call...
best regards,
Daniel
