One of the first kernel panic we hit when we try to increase the block size > 4k is inside create_page_buffers()[1]. Even though buffer.c function do not support large folios (folios > PAGE_SIZE) at the moment, these changes are required when we want to remove that constraint.
Willy had already mentioned that he wanted to convert create_page_buffers to folio_create_buffers but didn't get to it yet, so I decided to take a shot.
No functional changes introduced.
Changes since RFC[2]: - Renaming the helpers with folio_* - Calling folio_* helper version inside the *page* helper.
