unsigned int line_no-- undescribed --
Start handle that has been previously reserved with jbd2_journal_reserve.
This attaches handle to the running transaction (or creates one if there's
not transaction running). Unlike jbd2_journal_start this function cannot
block on journal commit, checkpointing, or similar stuff. It can block on
memory allocation or frozen journal though.
Return 0 on success, non-zero on error - handle is freed in that case.
