memstick: mspro_block: Fix an error code in mspro_block_issue_req()

2019-06-11T10:19:17Z

commit 61009f82a93f7c0b33cd9b3b263a6ab48f8b49d4 upstream. We accidentally changed the error code from -EAGAIN to 1 when we did the blk-mq conversion. Maybe a contributing factor to this mistake is that it wasn't obvious that the "while (chunk) {" condition is always true. I have cleaned that up as well.

mspro_block: convert to blk-mq

block: genhd: add 'groups' argument to device_add_disk

2018-09-28T14:30:28Z

Update device_add_disk() to take an 'groups' argument so that individual drivers can register a device with additional sysfs attributes. This avoids race condition the driver would otherwise have if these groups were to be created with sysfs_add_groups().

memstick: don't call blk_queue_bounce_limit

2018-05-11T21:07:55Z

All in-tree host drivers set up a proper dma mask and use the dma-mapping helpers. This means they will be able to deal with any address that we are throwing at them. 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.

mspro_block: remove pointless prep_fn

block: split out request-only flags into a new namespace

2016-10-28T14:45:17Z

A lot of the REQ_* flags are only used on struct requests, and only of use to the block layer and a few drivers that dig into struct request internals. This patch adds a new req_flags_t rq_flags field to struct request for them, and thus dramatically shrinks the number of common requests. It also removes the unfortunate situation where we have to fit the fields from the same enum into 32 bits for struct bio and 64 bits for struct request.

block: convert to device_add_disk()

2016-06-27T19:26:08Z

For block drivers that specify a parent device, convert them to use device_add_disk(). This conversion was done with the following semantic patch: @@ struct gendisk *disk; expression E; @@ - disk->driverfs_dev = E; ... - add_disk(disk); + device_add_disk(E, disk); @@ struct gendisk *disk; expression E1, E2; @@ - disk->driverfs_dev = E1; ... E2 = disk; ... - add_disk(E2); + device_add_disk(E1, E2); ...plus some manual fixups for a few missed conversions. Cc: Jens Axboe Cc: Keith Busch Cc: Michael S.
