Subject: fscrypt: convert bh_get_inode_and_lblk_num to use a folio
Date: Tue, 23 Apr 2024 23:55:32 +0100

Patch series "Remove page_mapping()".

There are only a few users left.  Convert them all to either call
folio_mapping() or just use folio->mapping directly.  


This patch (of 6):

Remove uses of page->index, page_mapping() and b_page.  Saves a call
to compound_head().
