These iomap changes are spun-off the XFS large atomic writes series at
https://lore.kernel.org/linux-xfs/86a64256-497a-453b-bbba-a5ac6b4cb056@oracle.com/T/#ma99c763221de9d49ea2ccfca9ff9b8d71c8b2677

The XFS parts there are not ready yet, but it is worth having the iomap
changes queued in advance.

Some much earlier changes from that same series were already queued in the
vfs tree, and these patches rework those changes - specifically the
first patch in this series does.

The most other significant change is the patch to rework how the bio flags
are set in the DIO patch.

The baseline is c7be0d72d551 (vfs/vfs-6.15.iomap) Merge patch series
"iomap preliminaries for large atomic write for xfs with CoW"

Applied to the vfs-6.15.iomap branch of the vfs/vfs.git tree.
Patches in the vfs-6.15.iomap branch should appear in linux-next soon.

Please report any outstanding bugs that were missed during review in a
new review to the original patch series allowing us to drop it.

It's encouraged to provide Acked-bys and Reviewed-bys even though the
patch has now been applied. If possible patch trailers will be updated.

Note that commit hashes shown below are subject to change due to rebase,
trailer updates or similar. If in doubt, please check the listed branch.
