James Bottomley 645a0c6c48 [SCSI] include linux/scatterlist.h in scsi_eh.h
Spotted by Paul Jackson <pj@sgi.com>

The error handler rework moved the scatterlist into a globally exposed
structure in scsi_eh.h; unfortunately, the scatterlist include needs
to move from scsi_error.c to scsi_eh.h to allow this to compile
universally.

Boaz Harrosh e1c234685c [SCSI] scsi_error: Refactoring scsi_error to facilitate in synchronous REQUEST_SENSE
- Drivers/transports that want to send a synchronous REQUEST_SENSE command
   as part of their .queuecommand sequence, have 2 new API's that facilitate
   in doing so and abstract them from scsi-ml internals.

   void scsi_eh_prep_cmnd(struct scsi_cmnd *scmd,
	struct scsi_eh_save *sesci, unsigned char *cmnd,
	int cmnd_size, int sense_bytes)

   Will hijack a command and prepare it for request sense if needed.
   And will save any later needed info into a scsi_eh_save structure.

   void scsi_eh_restore_cmnd(struct scsi_cmnd* scmd,
	struct scsi_eh_save *sesci);

   Will undo any changes done to a command by above function. Making
   it ready for completion.

 - Re-factor scsi_send_eh_cmnd() to use above APIs

Christoph Hellwig beb4048750 [SCSI] remove scsi_request infrastructure
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.

James Bottomley 33aa687db9 [SCSI] convert SPI transport class to scsi_execute
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.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
