Hello,

The current code does padding only for requests that we call
__blk_rq_map_user (bio_copy_user) for. You meant that if we create a
new flag like REQ_NEED_PADDING and set it in blk_rq_map_user,
blk_rq_map_sg can do padding only when it was set.
Yeap, that's what I meant.
Thanks, I see. Then, I have one question: blk_rq_map_user_iov doesn't
padding, thus libata still needs to adjust scatter list, right?
Yes but it doesn't, so blk_rq_map_user_iov() path is essentially broken
regarding padding at the moment. :-(
