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.
