Subject: [PATCH BUGFIX 0/1] block, bfq: a bugfix for stable merge
Date: Wed, 12 May 2021 11:43:51 +0200 [thread overview]
Message-ID: <20210512094352.85545-1-paolo.valente@linaro.org> (raw)
Hi,
this patch fixes a bug I've found while debugging a failure reported
by Yi Zhang [1].
This patch seems to make that failure disappear [1]. Yet it was tested
only together with other debug patches (which add logs and invariant
checks), so I don't know whether the other patches influenced the
outcome as well. At any rate, this patch does fix a bug.
Thanks,
Paolo
