It's because for the bvec iterator stuff and immutable bvecs, direct bi_idx usage tends to be either wrong or unnecessary - I had to audit all the uses in the kernel. Reason for doing it now is a later patch moves bi_idx (also bi_sector and bi_size) into a different struct - so doing these cleanup patches first means a bit less code churn. -- 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/
