The one=C2=A0thing I can think of is perhaps Koba was seeing multiple issues at time when he found this, like: https://lore.kernel.org/linux-crypto/20220901144712.1192698-1-koba.ko@canon= ical.com/ That was also being seen by an engineer here that was looking at client_count code. Koba, was this meant to be part of a series, or by itself? Regards, Jerry
