* SG: work with the SCSI fixed maximum allocations.James Bottomley2008-01-28
| | | | | | | | | | | | SCSI sg table allocation has a maximum size (of SCSI_MAX_SG_SEGMENTS, currently 128) and this will cause a BUG_ON() in SCSI if something tries an allocation over it. This patch adds a size limit to the chaining allocator to allow the specification of the maximum allocation size for chaining, so we always chain in units of the maximum SCSI allocation size.

* SG: Convert SCSI to use scatterlist helpers for sg chainingJens Axboe2008-01-28
| | | | | | | | Also change scsi_alloc_sgtable() to just return 0/failure, since it maps to the command passed in. ->request_buffer is now no longer needed, once drivers are adapted to use scsi_sglist() it can be killed. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* SG: Move functions to lib/scatterlist.c and add sg chaining allocator helpersJens Axboe2008-01-28
| | | | | | | Manually doing chained sg lists is not trivial, so add some helpers to make sure that drivers get it right. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
