ext4: fix mmap write protection for data=journal mode
Commit afb585a97f81 "ext4: data=journal: write-protect pages on
j_submit_inode_data_buffers()") added calls ext4_jbd2_inode_add_write()
to track inode ranges whose mappings need to get write-protected during
transaction commits. However the added calls use wrong start of a range
(0 instead of page offset) and so write protection is not necessarily
effective. Use correct range start to fix the problem.
