commit b968712a8cce12862e24d0461b073eaabe9cd3aa
Author: Cyril Hrubis <ch...@su...>
Date:   Tue Oct 22 19:50:31 2013 +0200

    misc: remove tcore testcase
    
    After a little bit of internet archeology and it seems that patch which
    introduced /proc/sys/kernel/core_dump_threads file never got accepted
    into mainline linux kernel. (I found some discussion about it around
    linux 2.4 and 2.5 development.)
    
    So it looks like this test was never working on mainline kernels.
