I appreciate you're trying to help, but the fourth report of a problem adds more noise than utility. https://lore.kernel.org/linux-mm/?q=shmem+folio shows emails about this from the cgelbot, Dan Carpenter, SeongJae Park, Colin King, Nathan Chancellor and Sebastian Siewior. So actually you were seventh, not fourth.
