[LTP] [PATCH] set_mempolicy05: require CONFIG_NUMA

[LTP] [PATCH] set_mempolicy05: require CONFIG_NUMA

[Avinesh Kumar via ltp]

On kernels without CONFIG_NUMA=y set_mempolicy() returns ENOSYS,
which the test misreports as TFAIL.

set_mempolicy05.c:105: TFAIL: set_mempolicy should fail with EFAULT or EINVAL, instead returned 38

Add .needs_kconfigs with CONFIG_NUMA=y

Hi Avinesh,

the patch looks good to me, but it's probably not enough. we will
need to implement the same concept for all set_mempolicy() tests,
since it's NUMA specific. We just missed this for all this time
apparently. Did you see the same errors for them as well?

Thanks for the review. Remaining set_mempolicy tests are checking for 
minimum two NUMA nodes and hence reports

tse_numa.c:200: TINFO: Found 1 NUMA memory nodes
tse_numa.c:141: TINFO: File '/sys/devices/system/node/node0/meminfo' 
does not exist! NUMA not enabled?
get_mempolicy02.c:60: TCONF: test requires at least one NUMA memory node

even on systems without CONFIG_NUMA=y.

But I also think that we should add
CONFIG_NUMA=y check in all these tests. Please confirm, I will send 
revised version.


Regards,
Avinesh

Yes please, let's fix them all already.

I suppose we do not need "#ifdef HAVE_NUMA_V2" anymore in the code.
Same for set_mempolicy02 etc
