[PATCH 0/5] block-job: drop BlockJob.blk

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

Hi all!

Block jobs usually operate with several block nodes, and better to
handle them symmetrically, than use one from s->common.blk and one from
s->target (or something like this). Moreover, generic blockjob layer has
no use of BlockJob.blk. And more-moreover, most of block-jobs don't
really use this blk. Actually only block-stream use it.

I've started this thing (unbinding block-job and its main node) long
ago. First step was removing bs->job pointer in b23c580c946644b. Then
block_job_drain was dropped in bb0c94099382b5273.

Now let's finally drop job->blk pointer.

Vladimir Sementsov-Ogievskiy (5):
  blockjob: implement and use block_job_get_aio_context
  test-blockjob-txn: don't abuse job->blk
  block/stream: add own blk
  test-bdrv-drain: don't use BlockJob.blk
  blockjob: drop BlockJob.blk field
