Hi Jens, this series takes advantage of the the new REQ_OP* scheme to further clean up the way how we classify bios and requests.
After the series both the bio and request have a field where the REQ_OP operation is stored in directly without any shiting around, and the coomon REQ_* flags can be ORed into directly as well. All the bio flags are now in the existing bi_flags field, and the many request-only flags are moved into a new field in struct request, which is split off cmd_flags. Last but not least this series ensures that we can encode the operational direction of a command in it's code. Currently the op_is_write, bio_data_dir and rq_data_dir helpers all assume that everything but a READ is a data out command. This surprisingly actually was true until this week, but the new shingled driver support conflicts with it - it's just that the relevant path didn't use any of these helpers so that issue wasn't noticed. -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
