Description corwin 2019-10-28 20:14:34 UTC

Description of problem:
In some rare circumstances, there is a race which could result in a VDO issuing I/O to the underlying storage after the VDO has been suspended.

Version-Release number of selected component (if applicable):
6.2.1.138

How reproducible:
Very rare. We have never directly observed this bug in the kernel. We have seen it quite rarely in our internal user-space unit testing.

Comment 4 Filip Suba 2020-03-16 14:13:06 UTC

Verified SanityOnly with vdo-6.2.2.117-13.el8.
