| * | SG: work with the SCSI fixed maximum allocations. | James Bottomley | 2008-01-28 | 1 | -14/+27 |
| | | | | | | | | | | | | | 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: Move functions to lib/scatterlist.c and add sg chaining allocator helpers | Jens Axboe | 2008-01-28 | 1 | -0/+281 |
| 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> | |||||
