fs: remove clean_page_buffers()
Patch series "Clean up the writeback paths".
Most of these patches verge on the trivial, converting filesystems that
just use block_write_full_page() to use mpage_writepages(). But as we saw
with Christoph's earlier patchset, there can be some "interesting"
gotchas, and I clearly haven't tested the majority of filesystems I've
touched here.
Patches 3 & 4 get rid of a lot of stack usage on architectures with larger
page sizes; 1024 bytes on 64-bit systems with 64KiB pages. It starts to
open the door to larger folio sizes on all architectures, but it's
certainly not enough yet.
Patch 14 is kind of trivial, but it's nice to get that simplification in.
This patch (of 14):
This function has been unused since the removal of bdev_write_page().
