As I said to Chris, there are a bunch of things I want to do to the code over the weekend, I wanted to get something out there before that though (raises the incentive to finish it) > - do not use hwgroup->wrq (die!) and do not add drive->special_buf, > just do what PM code does and other special commands do - use taskfile > (yes, dirty stack allocation) Doesn't work for split flush, ie issue a bunch of flushes to devices, then wait for them. I agree using ->wrq and special_buf is ugly as hell, though. > - SCSI -> IDE transform should die, please use something like REQ_FLUSH > and let subsystems deal with it That's what I wanted to avoid, adding more flags. However, if you see the comment in there this is being changed to ->issue_flush() instead. So it's dying, don't worry. > - ide_get_error_location() is cool but clean other places doing same thing > as you are duplicating existing code > (please use u64 not sector_t - you are getting raw info from the disk) Ok > - why does blkdev_issue_flush() add REQ_BLOCK_PC to rq->flags? Ehm, because it _is_ a REQ_BLOCK_PC? ;-) > - why are we doing pre-flush?
