The jbd_lock_bh_journal_head can be one global lock without a problem. But when I made jbd_lock_bh_state a global lock, I believe it deadlocked on me. So this one has to go into the buffer head. What do you mean with "put them in the journal", do you mean the journal_s structure? Is there a safe way to get to that structure from the buffer head? The state lock is used quite a bit and it gets tricky trying to figure out how to use other structures wrt buffer_heads at all the locations that use jbd_lock_bh_state. -- Steve - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
