Subject: New kernel warning triggered by blktests
Date: Fri, 23 Apr 2021 13:38:56 -0700	[thread overview]
Message-ID: <45925919-ea46-1e38-2983-87b12c12003a@acm.org> (raw)

Hi Changheun,

If I run blktest srp/001 then a kernel warning appears that I haven't
seen before. I think this is a side-effect of the patch that limits the
bio size. Please take a look.

Thanks,

Bart.
