Hi all,
I have a question about function jbd2__journal_restart().
If we call this function when there's not more credits,
it may commit the handle's transaction and start another one.
So a handle can be attached to 2 transaction and can not ensure the
consistency. It is the caller's responsibility to keep things consistently
before call jbd2__journal_restart(), right?
Thanks very much.
