I also think you can add a separate patch to fix this comment in doc or 
in  tst_test.h for other struct pointers.

         /*
          * NULL-terminated array to be allocated buffers.
          */
         struct tst_buffers *bufs;

         /*
          * NULL-terminated array of capability settings
          */
         struct tst_cap *caps;
