remove most callers of write_one_page v4
Hi all,
this series removes most users of the write_one_page API. These helpers
internally call ->writepage which we are gradually removing from the
kernel.
Changes since v3:
- drop all patches merged in v6.3-rc1
- re-add the jfs patch
Changes since v2:
- more minix error handling fixes
Changes since v1:
- drop the btrfs changes (queue up in the btrfs tree)
- drop the finaly move to

[PATCH 00/12] block/bio, fs: convert put_page() to put_user_page*()
From: John Hubbard <jhubbard at nvidia.com>
Hi,
This is mostly Jerome's work, converting the block/bio and related areas
to call put_user_page*() instead of put_page(). Because I've changed
Jerome's patches, in some cases significantly, I'd like to get his
feedback before we actually leave him listed as the author (he might
want to disown some or all of these).
