Yes, that is correct. Also I have realized that before patches I've already
mentioned are applicable, you will also need to pick up:
9462f770eda8 ("ext4: Update stale comment about write constraints")
c8e8e16dbbf0 ("ext4: Use nr_to_write directly in mpage_prepare_extent_to_map()")
3f5d30636d2a ("ext4: Mark page for delayed dirtying only if it is pinned")
f1496362e9d7 ("ext4: Don't unlock page in ext4_bio_write_page()")
eaf2ca10ca4b ("ext4: Move page unlocking out of mpage_submit_page()")
d8be7607de03 ("ext4: Move mpage_page_done() calls after error handling")
3f079114bf52 ("ext4: Convert data=journal writeback to use ext4_writepages()")
e6c28a26b799 ("ext4: Fix warnings when freezing filesystem with journaled data")
This commit actually gets reverted in the series of patches I have
already mentioned.
So sadly the backport is even larger than what I originally thought.
