The zero iterator can work in folio-sized chunks instead of page-sized
chunks.  This will save a lot of page cache lookups if the file is cached
in multi-page folios.

hch's dax decoupling series notwithstanding,

Though TBH I am kinda wondering how the two of you plan to resolve those
kinds of differences -- I haven't looked at that series, though I think
this one's been waiting in the wings for longer?

I haven't looked at that series either

Heck, I wonder how Matthew plans to merge all this given that it touches
mm, fs, block, and iomap...?

I'm planning on sending a pull request to Linus on Monday for the first
few patches in this series:
https://git.infradead.org/users/willy/pagecache.git/shortlog/refs/heads/for-next

Then I was hoping you'd take the block + fs/buffer + iomap pieces for
the next merge window.
