From 985cac8f200443ad952becc03b07c51ff4f80983 Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Thu, 6 May 2021 17:13:57 +0300 Subject: blockjob: drop BlockJob.blk field It's unused now (except for permission handling)[*]. The only reasonable user of it was block-stream job, recently updated to use own blk. And other block jobs prefer to use own source node related objects. So, the arguments of dropping the field are: - block jobs prefer not to use it - block jobs usually has more then one node to operate on, and better to operate symmetrically (for example has both source and target blk's in specific block-job state structure) *: BlockJob.blk is used to keep some permissions. We simply move permissions to block-job child created in block_job_create() together with blk. In mirror, we just should not care anymore about restoring state of blk. Most probably this code could be dropped long ago, after dropping bs->job pointer. Now it finally goes away together with BlockJob.blk itself. iotest 141 output is updated, as "bdrv_has_blk(bs)" check in qmp_blockdev_del() doesn't fail (we don't have blk now). Still, new error message looks even better. In iotest 283 we need to add a job id, otherwise "Invalid job ID" happens now earlier than permission check (as permissions moved from blk to block-job node).
