hi, Stefan Roesch, we reported "[linux-next:master] [mm/ksm] 5e924ff54d: ltp.ksm01_1.fail" in https://lore.kernel.org/all/202311031548.66780ff5-oliver.sang@xxxxxxxxx/ when this commit is in linux-next/master. now we noticed this commit is merged in mainline, and we still observed same issue. just FYI.
