JBD2_JOURNAL_WIPE(9)                The Linux Journalling API                JBD2_JOURNAL_WIPE(9)



NAME
       jbd2_journal_wipe - Wipe journal contents

SYNOPSIS
       int jbd2_journal_wipe(journal_t * journal, int write);

ARGUMENTS
       journal
           Journal to act on.

       write
           flag (see below)

DESCRIPTION
       Wipe out all of the contents of a journal, safely. This will produce a warning if the
       journal contains any valid recovery information. Must be called between journal_init_*()
       and jbd2_journal_load.

       If 'write' is non-zero, then we wipe out the journal on disk; otherwise we merely suppress
       recovery.
