* treewide: Add SPDX license identifier for missed filesThomas Gleixner2019-05-211-0/+1
| | | | | | | | | | | | | | | | | Add SPDX license identifiers to all files which: - Have no license information of any form - Have EXPORT_.*_SYMBOL_GPL inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* ide: don't use req->specialChristoph Hellwig2018-11-101-1/+1

* block: introduce new block status code typeChristoph Hellwig2017-06-091-8/+8
| | | | | | | | | | | | | | | | | | | | | | | 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.

* scsi: introduce a result field in struct scsi_requestChristoph Hellwig2017-04-201-18/+18
| | | | | | | | | | | | | | | This passes on the scsi_cmnd result field to users of passthrough requests. Currently we abuse req->errors for this purpose, but that field will go away in its current form. Note that the old IDE code abuses the errors field in very creative ways and stores all kinds of different values in it. I didn't dare to touch this magic, so the abuses are brought forward 1:1.

* block: fold cmd_type into the REQ_OP_ spaceChristoph Hellwig2017-01-311-1/+1
| | | | | | | | | | | | | | | 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.

* ide: don't abuse cmd_typeChristoph Hellwig2017-01-311-2/+2
| | | | | | | | | | | | | | Currently the legacy ide driver defines several request types of it's own, which is in the way of removing that field entirely. Instead add a type field to struct ide_request and use that to distinguish the different types of IDE-internal requests. It's a bit of a mess, but so is the surrounding code..

* block: split scsi_request out of struct requestChristoph Hellwig2017-01-271-1/+1
| | | | | | | | | | And require all drivers that want to support BLOCK_PC to allocate it as the first thing of their private data. To support this the legacy IDE and BSG code is switched to set cmd_size on their queues to let the block layer allocate the additional space.
