JBD2_JOURNAL_START_R(9)             The Linux Journalling API             JBD2_JOURNAL_START_R(9)



NAME
       jbd2_journal_start_reserved - start reserved handle

SYNOPSIS
       int jbd2_journal_start_reserved(handle_t * handle, unsigned int type,
                                       unsigned int line_no);

ARGUMENTS
       handle
           handle to start

       type
           -- undescribed --

       line_no
           -- undescribed --

DESCRIPTION
       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.
