Subject: t_firstblock assert triggered from dedup in generic/051
Date: Wed, 11 Jul 2018 20:42:41 +0200 [thread overview]
Message-ID: <20180711184241.GA4949@lst.de> (raw)
I ran into this when testing the rebase of my cow optimization
series to the 4.19-merge branch, but from a quick glance it really
looks like the t_firstblock series might be at faul. Feel free
to discard if you think it is not, I will retest with my patches
tomorrow.
