[GIT PATCH linux-2.6-block] block: cleanup patches, take#3

[Tejun Heo <tj@kernel.org>]

Hello,

Upon ack, please pull from the following git tree, which pulls in
linux-2.6-ide#for-next into linux-2.6-block#for-next and applies this
patchset on top of it.

 git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git block-cleanup

This is the third take of block-cleanup-patches.  Changes from the
last take[L] are

* All ide changes including L0001-0003 are separated out and merged
  through linux-2.6-ide#for-next and pulled into
  linux-2.6-block#for-next.

* L0015-block-kill-end_request.patch replaced with
  0012-block-replace-end_request-with-__-blk_end_reques.patch.

* L0016-ubd-simplify-block-request-completion.patch
  L0017-block-clean-up-unnecessary-stuff-from-block-drivers.patch are
  postponed to later patchset.

* 0013-0014 to kill rq->data added.

* Updated to the current #for-next.

 0001-block-merge-blk_invoke_request_fn-into-__blk_run_.patch
 0002-block-kill-blk_start_queueing.patch
 0003-block-don-t-set-REQ_NOMERGE-unnecessarily.patch
 0004-block-cleanup-REQ_SOFTBARRIER-usages.patch
 0005-block-clean-up-misc-stuff-after-block-layer-timeout.patch
 0006-block-reorder-request-completion-functions.patch
 0007-block-reorganize-request-fetching-functions.patch
 0008-block-kill-blk_end_request_callback.patch
 0009-block-clean-up-request-completion-API.patch
 0010-block-move-rq-start_time-initialization-to-blk_rq_.patch
 0011-block-implement-and-use-__-blk_end_request_all.patch
 0012-block-replace-end_request-with-__-blk_end_reques.patch
 0013-block-don-t-abuse-rq-data.patch
 0014-block-kill-data.patch

0001-0011 are mostly identical to L0004-0014.  L0015 incorrectly
replaced end_request() with __blk_end_request_all().  0012 adds
[__]blk_end_request_cur() and replaces end_request() with it.

With ide changes pulled in, omap is the only user of rq->data, 0013
makes it use only rq->special and 0014 kills rq->data.

This patchset is on top of

linux-2.6-block#for-next(a95320f3ede3f028837a621715cd352e83ffe7c2)
+ linux-2.6-ide#for-next(2ecf0a57c60dcb588f310d94412118e15c510532)
