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.
Theodore Ts'o (3):
jbd2: Use atomic variables to avoid taking t_handle_lock in
jbd2_journal_stop
jbd2: Change j_state_lock to be a rwlock_t
jbd2: Remove t_handle_lock from start_this_handle()
