Subject: [Qemu-devel] [PULL 03/11] tests/block-job-txn: Don't start block job before adding to txn
Date: Tue, 11 Apr 2017 20:26:24 +0800	[thread overview]
Message-ID: <20170411122632.14050-4-famz@redhat.com> (raw)
In-Reply-To: <20170411122632.14050-1-famz@redhat.com>

Previously, before test_block_job_start returns, the job can already
complete, as a result, the transactional state of other jobs added to
the same txn later cannot be handled correctly.

Move the block_job_start() calls to callers after
block_job_txn_add_job() calls.
