- int jbd2_journal_wipe(journal_t * journal, int write);
- Journal to act on.
- flag (see below)
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.
