I guess what you mean is splitting commands into multiple se_tasks, which in some form will still be needed, but I suspect it's more efficient to not create multiple data structures for the iblock case, but rather create bios on the fly while parsing the S/G list, both for IBLOCK and PSCSI. If we can't completely get rid of the se_tasks at least only using them for data I/O, and avoiding their creation for the internally handled metadata CDBs seems like another nice optimization. -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
