* block: split scsi_request out of struct requestChristoph Hellwig2017-01-271-0/+30
| | | | | | | | | | 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.

* [SCSI] remove scsi_request infrastructureChristoph Hellwig2006-06-101-54/+0Star
| | | | | | | | | With Achim patch the last user (gdth) is switched away from scsi_request so we an kill it now. Also disables some code in i2o_scsi that was broken since the sg driver stopped using scsi_requests.

* [SCSI] remove scsi_wait_reqChristoph Hellwig2005-11-061-3/+0Star
| | | | | | | | This function has been superceeded by the block request based interfaces and is unused (except for the uncompilable cpqfc driver). Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] convert SPI transport class to scsi_executeJames Bottomley2005-08-281-4/+0Star
| | | | | | | | | | | This one's slightly more difficult. The transport class uses REQ_FAILFAST, so another interface (scsi_execute) had to be invented to take the extra flag. Also, the sense functions are shifted around to allow spi_execute to place data directly into a struct scsi_sense_hdr. With this change, there's probably a lot of unnecessary sense buffer allocation going on which we can fix later. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] convert the remaining mid-layer pieces to scsi_execute_reqJames Bottomley2005-08-281-15/+0Star
| | | | | | | After this, we just have some drivers, all the ULDs and the SPI transport class using scsi_wait_req(). Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] use scatter lists for all block pc requests and simplify hw handlersJames Bottomley2005-08-281-0/+3
| | | | | | | | | | Original From: Mike Christie <michaelc@cs.wisc.edu> Add scsi_execute_req() as a replacement for scsi_wait_req() Fixed up various pieces (added REQ_SPECIAL and caught req use after free) Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* Linux-2.6.12-rc2Linus Torvalds2005-04-171-0/+73
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
