Subject: [PATCH v14 11/13] iotests: 30: prepare to COR filter insertion by stream job
Date: Sat,  5 Dec 2020 01:07:56 +0300	[thread overview]
Message-ID: <20201204220758.2879-12-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20201204220758.2879-1-vsementsov@virtuozzo.com>

test_stream_parallel run parallel stream jobs, intersecting so that top
of one is base of another. It's OK now, but it would be a problem if
insert the filter, as one job will want to use another job's filter as
above_base node.

Correct thing to do is move to new interface: "bottom" argument instead
of base. This guarantees that jobs don't intersect by their actions.
