DESCRIPTION

19       We make sure that the transaction can guarantee at least nblocks of
20       modified buffers in the log. We block until the log can guarantee that
21       much space.

23       This function is visible to journal users (like ext3fs), so is not
24       called with the journal already locked.

27       failure.
