Hi all,

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

Brian

v4:
- Whitespace and variable naming fixes.
- Split off patch 4 to a separate post.
v3: https://lore.kernel.org/linux-fsdevel/[e-mail]/
- 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/[e-mail]/
- 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.
v1: https://lore.kernel.org/linux-fsdevel/[e-mail]/

Brian Foster (3):
  iomap: reset per-iter state on non-error iter advances
  iomap: lift zeroed mapping handling into iomap_zero_range()
  iomap: elide flush from partial eof zero range
