Question concerning the EXT3 Journaling code
...in the hopes that I can identify a place where they 
may be experiencing unexpected delays.
This debugging lead me to look at the code in start_this_handle(), 
contained in file fs/jbd/transaction.c, and I have a question concerning 
the wake_up() logic for the thread which may go to sleep on 
<j_wait_transaction_locked>.
The thread will sleep as long as <j_barrier_count> is non-zero:
         repeat:
                 spin_lock(&journal->j_state_lock);
                 ...
                 if (journal->j_barrier_count) {
                         spin_unlock(&journal->j_state_lock);...

[PATCH -v2 0/3] jbd2 scalability patches
This version fixes three bugs in the 2nd patch of this series that
caused kernel BUG when the system was under race.  We weren't accounting
with t_oustanding_credits correctly, and there were race conditions
caused by the fact the I had overlooked the fact that
__jbd2_log_wait_for_space() and jbd2_get_transaction() requires
j_state_lock to be write locked.
