Subject: [PATCH] jbd/jbd2: add pointer type conversion on void *arg from void
 * to journal_t * explicitly in kjournald/kjournald2

The patch is against 3.0

The arg of kjournald/kjournald2 is void *, and points to type
journal_t. We should convert it to journal_t * explicitly in
the kjournald/kjournald2 function body.
