I understand that's true for XFS, but it's not true throughout the
rest of the kernel. This file isn't even consistent:

buffered-io.c:static inline struct iomap_page *to_iomap_page(struct page *page)
buffered-io.c:static inline bool iomap_block_needs_zeroing(struct inode
buffered-io.c:static int iomap_zero(struct inode *inode, loff_t pos, unsigned offset,
buffered-io.c:static void iomap_writepage_end_bio(struct bio *bio)
buffered-io.c:static int __init iomap_init(void)

(i just grepped for ^static so there're other functions not covered by this)

The other fs/iomap/ files are equally inconsistent.
