Subject: [PATCH blktests 0/2] Add scsi-stress-remove to blktests
Date: Wed, 12 Dec 2018 18:09:57 -0500	[thread overview]
Message-ID: <20181212230959.69975-1-dennis@kernel.org> (raw)

Hi,

Ming Lei's scsi-stress-remove test found a bug in blkg destruction [1]
where bios being created when the request_queue was being cleaned up
threw a NPE in blkg association. The fix is currently being discussed in
[2]. To make this test more accessible, I've ported it to blktests with
Ming Lei's copyright. I've tested this in my qemu instance and verified
we do not see the NPE on a fixed kernel.

Ming, please let me know if you have any objections.
