I'm still working to convert sg (st and osst) to use the blk mapping API. Here's two patches for these functions that I like to be merged into mainline before that work. The first patch is a repost with a proper description, a patch to move the padding adjustment from blk_rq_map_user to blk_rq_map_sg. This patch affects only libata and I tested this patch with my CD-R drive using libata and it works fine. Tejun, does this change break something in libata? The second patch changes blk_rq_unmap_user to take a request instead of a bio. A pointer to a bio is added to request struct (Mike did the same thing when adding multiple bio support to the API). I know that it's not nice to add something to request struct, however, the asymmetry of the map/unmap API lead to trouble easily (it led to bugs in the past). I think that it worth doing that to avoid future trouble.
