Subject: buffer: convert init_page_buffers() to folio_init_buffers()
has been removed from the -mm tree. Its filename was

of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: buffer: convert init_page_buffers() to folio_init_buffers()
Date: Mon, 12 Jun 2023 22:01:38 +0100
Use the folio API and pass the folio from both callers. Saves a hidden
call to compound_head().
