commit 6ba0e7dc64a5 ("jbd2: introduce jbd2_inode dirty range scoping")
allow us scoping each of the inode dirty ranges associated with a given
transaction, and ext4 already does this way.
Now let's also use the newly introduced jbd2_inode dirty range scoping
to prevent us from waiting forever when trying to complete a journal
transaction in ocfs2.

Hi Joseph,
Originally, ocfs2_jbd2_file_inode() is a wrapper of jbd2 routine
jbd2_journal_file_inode() which has been renamed
by Jan Kara long ago. (41617e1a8dec9fe082ba5dec26bacb154eb55482)
So how about we change ocfs2_jbd2_file_inode to
ocfs2_jbd2_inode_add_write() this time within your patch?
Thanks,
Changwei

Sure, I'll make this change along with other opinions in v2.

Perhaps ocfs2_jbd2_ranged_write() would be more informative if you're renaming
this function?
Aside from these nits, this all looked good to me. You can add:
