[PATCH v4 0/3] iomap: zero range flush fixes

[Brian Foster <bfoster@redhat.com>]

Hi all,

Here's v4 of the zero range flush improvements. No real major changes
here, mostly minor whitespace, naming issues, etc.

v4:
- Whitespace and variable naming fixes.
- Split off patch 4 to a separate post.
v3: https://lore.kernel.org/linux-fsdevel/20241108124246.198489-1-bfoster@redhat.com/
- Added new patch 1 to always reset per-iter state in iomap_iter.
- Dropped iomap_iter_init() helper.
- Misc. cleanups.
- Appended patch 4 to warn on zeroing beyond EOF.
v2: https://lore.kernel.org/linux-fsdevel/20241031140449.439576-1-bfoster@redhat.com/
- Added patch 1 to lift zeroed mapping handling code into caller.
- Split unaligned start range handling at the top level.
- Retain existing conditional flush behavior (vs. unconditional flush)
  for the remaining range.
