The patch changed sizeof(st->attrs) to sizeof(*st->attrs). The type of st->attrs is struct attribute **, so both sizeofs return the same value (the size of an pointer) and the code happens to work, still the later is semantically more correct. >> The semantic patch that makes this output is available >> in scripts/coccinelle/misc/noderef.cocci. >> >> More information about semantic patching is available at >> http://coccinelle.lip6.fr/ > > Can you remove those two boiler plate lines? We all have google. It would be nice to have a pointer to the specific cocci script used to generate the patch though. - Lars -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
