I don't remember the detail of xarray, but my cacheutils extension
module also checks this without any error, in its callback function [1].
So how about implementing like this?
if (!is_page_ptr(slot, &phys))
return FALSE;

Also, I could reproduc it and actually they can be ignored because the
inode's nrpages equals to the number of pages in the nodes:
crash> files -n ffff9c50cbe59920
INODE NRPAGES
ffff9c50cbe59920 96 <<<
files: page_to_nid: invalid page: afe27
files: page_to_nid: invalid page: b35db
files: page_to_nid: invalid page: b35df
...
files: page_to_nid: invalid page: 24ced
NODE PAGES
0 96 <<<
Thanks,
Kazu
