remove the obsolete hd driver

2017-04-05T15:50:34Z

This driver is for pre-IDE hardisk that are only found in PC from the stoneage of personal computing, and which we don't support elsewhere in the kernel these days. It's also been marked broken forever. Signed-off-by: Christoph Hellwig Reviewed-by: Martin K. Petersen 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.

Replace with globally

2016-12-24T19:46:01Z

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

block: hd: remove deprecated IRQF_DISABLED

2014-10-01T14:16:07Z

This patch removes the use of the IRQF_DISABLED flag from drivers/block/hd.c It's a NOOP since 2.6.35 and it will be removed one day. This also removes a related comment which is obsolete too. Signed-off-by: Michael Opdenacker Signed-off-by: Jens Axboe

block: remove struct request buffer member

2014-04-15T20:03:02Z

This was used in the olden days, back when onions were proper yellow. Basically it mapped to the current buffer to be transferred. With highmem being added more than a decade ago, most drivers map pages out of a bio, and rq->buffer isn't pointing at anything valid. Convert old style drivers to just use bio_data(). For the discard payload use case, just reference the page in the bio. Signed-off-by: Jens Axboe

block: remove wrappers for request type/flags

2010-08-07T16:17:56Z

Remove all the trivial wrappers for the cmd_type and cmd_flags fields in struct requests. This allows much easier grepping for different request types instead of unwinding through macros. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe
