In linux kernel since version 2.6.25 (release Date: 2008-04-16)  
This option provides a kernel module that can be used to test
the kernel stack backtrace code. This option is not useful
for distributions or general kernels, but only for kernel
developers working on architecture code.

Note that if you want to also test saved backtraces, you will
have to enable STACKTRACE as well.

Say N if you are unsure.
