Pankaj recently added folio_create_empty_buffers() as the folio
equivalent to create_empty_buffers(). This patch set finishes
the conversion by first converting all remaining filesystems
to call folio_create_empty_buffers(), then renaming it back
to create_empty_buffers(). I took the opportunity to make a few
simplifications like making folio_create_empty_buffers() return the head
buffer and extracting get_nth_bh() from nilfs2.
A few of the patches in this series aren't directly related to
create_empty_buffers(), but I saw them while I was working on this and
thought they'd be easy enough to add to this series. Compile-tested only,
other than ext4.
v2:
- Added the patch to fix the return type from grow_dev_page()
- Fixed typo in subject line noticed by Andreas
- Fixed missed assignment to 'bh' spotted by Andreas
- Exported folio_copy() spotted by Ryusuke
- Added various Reviewed-by tags from Pankaj, Ryusuke & Andreas
