A couple issues.  First, this email wasn't sent to the subsystem's
mailing list (linux-crypto@vger.kernel.org in this case).  That greatly
reduces the number of people who are made aware that this didn't get
automatically backported.

Second, the upstream commit cherry-picks to 6.1, 5.15, and 5.10 without
conflict.  (The file being changed was renamed between 6.1 and 6.6, but
'git cherry-pick' handles that automatically.)

I don't know what you're doing exactly that caused it to be
unnecessarily marked as FAILED.  But whatever it is, it's not working,
and it is causing backports to be missed.
