Hi, I have a question on this function in the $subject.In https://marc.info/?l=linux-kernel&m=154466776014573&w=2, Martin recommended using this function.
However, for our driver, we find it returns 0 always, as rq->q->integrity.interval_exp = 0.
Our host is advertised DIF capable only. I assume that interval_exp would be set somehow from sd_dif_config_host()->blk_integrity_register(), but we don't follow this path for !DIX.
What would we be missing that this is unset? Thanks, John
