[PATCH 5/6] memory-failure: Convert truncate_error_page to truncate_error_folio

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Both callers now have a folio, so pass it in.  Nothing downstream was
expecting a tail page; that's asserted in generic_error_remove_page(),
for example.
