block: sanitize blk_get_request calling conventions

Instead move it to the callers. Those that either don't use bio_data() or page_address() or are specific to architectures that do not support highmem are skipped. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

block: introduce new block status code type

2017-06-09T15:27:32Z

Currently we use nornal Linux errno values in the block layer, and while we accept any error a few have overloaded magic meanings. This patch instead introduces a new blk_status_t value that holds block layer specific status codes and explicitly explains their meaning. Helpers to convert from and to the previous special meanings are provided for now, but I suspect we want to get rid of them in the long run - those drivers that have a errno input (e.g. networking) usually get errnos that don't know about the special block layer overloads, and similarly returning them to userspace will usually return somethings that strictly speaking isn't correct for file system operations, but that's left as an exercise for later. For now the set of errors is a very limited set that closely corresponds to the previous overloaded errno values, but there is some low hanging fruite to improve it. blk_status_t (ab)uses the sparse __bitwise annotations to allow for sparse typechecking, so that we can easily catch places passing the wrong values.

pd: don't check blk_execute_rq return value.

2017-04-20T18:16:10Z

The driver never sets req->errors, so blk_execute_rq will always return 0. Signed-off-by: Christoph Hellwig Reviewed-by: Bart Van Assche Reviewed-by: Johannes Thumshirn Signed-off-by: Jens Axboe

block: fold cmd_type into the REQ_OP_ space

2017-01-31T21:00:44Z

Instead of keeping two levels of indirection for requests types, fold it all into the operations. The little caveat here is that previously cmd_type only applied to struct request, while the request and bio op fields were set to plain REQ_OP_READ/WRITE even for passthrough operations. Instead this patch adds new REQ_OP_* for SCSI passthrough and driver private requests, althought it has to add two for each so that we can communicate the data in/out nature of the request.
