2017-12-22test-bdrv-drain: Test graph changes in drained sectionKevin Wolf1-0/+80
Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-12-22test-bdrv-drain: Recursive draining with multiple parentsKevin Wolf1-0/+74
Test that drain sections are correctly propagated through the graph. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-12-22test-bdrv-drain: Test behaviour in coroutine contextKevin Wolf1-0/+59
If bdrv_do_drained_begin/end() are called in coroutine context, they first use a BH to get out of the coroutine context. Call some existing tests again from a coroutine to cover this code path. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-12-22test-bdrv-drain: Tests for bdrv_subtree_drainKevin Wolf1-1/+26
Add a subtree drain version to the existing test cases. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-12-22test-bdrv-drain: Test nested drain sectionsKevin Wolf1-0/+57
Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-12-22block: Don't block_job_pause_all() in bdrv_drain_all()Kevin Wolf1-6/+4
Block jobs are already paused using the BdrvChildRole drain callbacks, so we don't need an additional block_job_pause_all() call. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-12-22test-bdrv-drain: Test drain vs. block jobsKevin Wolf1-0/+121
Block jobs must be paused if any of the involved nodes are drained. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-12-22test-bdrv-drain: Test bs->quiesce_counterKevin Wolf1-0/+45
This is currently only working correctly for bdrv_drain(), not for bdrv_drain_all(). Leave a comment for the drain_all case, we'll address it later. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-12-22test-bdrv-drain: Test callback for bdrv_drainKevin Wolf1-7/+62
The existing test is for bdrv_drain_all_begin/end() only. Generalise the test case so that it can be run for the other variants as well. At the moment this is only bdrv_drain_begin/end(), but in a while, we'll add another one. Also, add a backing file to the test node to test whether the operations work recursively.

2017-12-22test-bdrv-drain: Test BlockDriver callbacks for drainKevin Wolf1-0/+137
This adds a test case that the BlockDriver callbacks for drain are called in bdrv_drained_all_begin/end(), and that both of them are called exactly once. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
