Hi all,
this series resurrects and forward ports ports larger parts of the
"block: don't drain file system I/O on del_gendisk" series from Ming,
but does not remove the draining in del_gendisk, but instead the one
in the sd driver, which always was a bit ad-hoc. As part of that sd
and sr are switched to use the new ->free_disk method to avoid having
to clear disk->private_data and the way to lookup the SCSI ULP is
cleaned up as well.
