I gave it a thought. Overhead was 4 bytes more per slave structure + more cycles in filter routine (arrays are more faster :) ). Because the DT capture is a one time activity, its better to save time in filter fns. > And one more thing.

Will do that in a separate patch, outside the scope of this patchset. :) -- viresh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
