Then the advice is incorrect for older kernels. If LTP should still run
nicely for users of older kernels then perhaps something like this is better:

-       echo modprobe capability or recompile your kernel with
-       echo CONFIG_SECURITY_CAPABILITIES=y.
+       if tst_kvercmp 2 6 24 ; then
+               echo modprobe capability or recompile your kernel with
+               echo CONFIG_SECURITY_CAPABILITIES=y.
+       elif tst_kvercmp 2 6 27 ; then
+               echo recompile your kernel with CONFIG_SECURITY_CAPABILITIES=y.
+       else
+               echo recompile your kernel with 
CONFIG_SECURITY_FILE_CAPABILITIES=y.
+       fi
