[PATCH] libnuma: checking of sucessfull allocations in numademo

From: Petr Holasek <[email protected]>

This patch is based on BZ 
https://bugzilla.redhat.com/show_bug.cgi?id=707138
where too big argument for numademo caused segfault.

Only simple check of returned pointer from numa_alloc*
calls was added.
