[PULL 07/53] iotests: add #310 to test bottom node in COR driver |
Date: |
Tue, 26 Jan 2021 15:19:30 +0100 |
From: Andrey Shinkevich <andrey.shinkevich@virtuozzo.com>
The test case #310 is similar to #216 by Max Reitz. The difference is
that the test #310 involves a bottom node to the COR filter driver.
