I guess all the invalid page is "0" which means an empty page cache slot, so could you please try this:

No, last time it printed some invalid pages(not only zero values), you could refer to this:

crash> files -n ffff8ea84c130938
      INODE        NRPAGES
ffff8ea84c130938    62527

I cannot find the kernel version in your email.

Sure, this issue was reproduced on the 6.5.0-rc1, I mentioned the kernel version in this link, maybe it is helpful for you.
