Hi Andrew, Jens, James,
The following patches are the revised version to use lld's private data
instead of backing_dev_info.state for exporting lld busy state.
Please review and give me your opinion.
If all of you have no problem, I'll re-send the patches separately
to each maintainer, Jens and James.
The patches are created on the following commit of for-2.6.28
in linux-2.6-block, but the scsi part can be also applied to
scsi-post-merge-2.6.
