2.6.22 API change Unused destroy_dirty_buffers arg removed from prototype. 2.6.24 API change Empty write barriers are now supported and we should use them. 2.6.24 API change Size argument dropped from bio_endio and bi_end_io, because the bi_end_io is only called once now when the request is complete. There is no longer any need for a size argument. This also means that partial IO's are no longer possibe and the end_io callback should not check bi->bi_size. Finally, the return type was updated to void. 2.6.28 API change open/close_bdev_excl() renamed to open/close_bdev_exclusive(). 2.6.29 API change BIO_RW_SYNC renamed to BIO_RW_SYNCIO.
