Date: Wed, 12 Jun 2024 15:18:23 +0800

Patch series "Some cleanups for memory-failure", v3.

This series contains a few cleanup patches to avoid exporting unused
function, add helper macro, fix some obsolete comments and so on.  More
details can be found in the respective changelogs.  


This patch (of 13):

Remove unneeded page != NULL check.  pfn_to_page() won't return NULL.  No
functional change intended.
