[PATCH 0/3] block changes for request-based dm-multipath

[Kiyoshi Ueda <k-ueda@ct.jp.nec.com>]

Hi Jens,

The following patches are changes of the block layer for
request-based dm-multipath.
The patches are created on the following commit of for-2.6.28
in linux-2.6-block.
---------------------------------------------------------------
commit 1fd75f9b2e1c273ab145c9bf3e7a8afcbd8be87a
Author: Jens Axboe <jens.axboe@oracle.com>

    block: cleanup some of the integrity stuff in blkdev.h
---------------------------------------------------------------

No major changes since the last post (http://lkml.org/lkml/2008/9/12/100),
except for following up the differences from 2.6.27-rc6.
(As I said, I don't include patches for refactoring of similar
 interfaces at this time.  The refactoring patches will be posted
 after the request-based dm-multipath work is done.)

Summary of the patches:
  1/3: block: add a request data completion interface
  2/3: block: add a request submission interface
  3/3: block: add a queue flag for request stacking support

Please review and apply.

Thanks,
Kiyoshi Ueda
