This series aims to fix the CVE-2025-38073 for 6.1 LTS. Which is fixed
by c0e473a0d226 ("block: fix race between set_blocksize and read
paths"). This patch is built on top multiple refactors that where
merged on 6.6. The needed dependecies are:
- e003f74afbd2 ("filemap: add a kiocb_invalidate_pages helper")
- c402a9a9430b ("filemap: add a kiocb_invalidate_post_direct_write
helper")
- 182c25e9c157 ("filemap: update ki_pos in generic_perform_write")
- 44fff0fa08ec ("fs: factor out a direct_write_fallback helper")
- 727cfe976758 ("block: open code __generic_file_write_iter for
blkdev writes")
Also backport follow up fixes:
- fb881cd76045 ("nilfs2: fix deadlock warnings caused by lock
dependency in init_nilfs()").
- 8287474aa5ff ("direct_write_fallback(): on error revert the ->ki_pos
update from buffered write")
Thanks,
