Ohh, thx for the pointer. Could you please next time add a tag like

Fixes: 18a25da84354 ("dm: ensure bio submission follows a depth-first
tree walk")

to the commit? For details see
Documnetation/process/submitting-patches.rst section 2 and 13:
https://www.kernel.org/doc/html/latest/process/submitting-patches.html

That would have saved both of us this conversation. In addition I head
that at least one big Linux distributor is using those tags when
backporting changes to make sure all relevant fixes for a particular
backported commit get backported as well.

I just asked you to help me make regression tracking work a little bit
easier. I'm neither planing to enforce this nor in a position to do so,
thus feel free to not do what I asked for; that's totally fine for me.
Especially as those tags are only a interim solution afaics (one that I
don't like to much myself; but they sometimes help connecting the
various dots in the phase where the commit that introduced a regression
is not yet known).

Ciao, Thorsten
