On an SMP ARM system running ext4, I've received a report that the first J_ASSERT in jbd2_journal_commit_transaction has been triggering: J_ASSERT(journal->j_running_transaction != NULL); While investigating possible causes for this problem, I noticed that __jbd2_log_start_commit() is getting called with j_state_lock only read-locked, in spite of the fact that it's possible for it might j_commit_request. Fix this by grabbing the necessary information so we can test to see if we need to start a new transaction before dropping the read lock, and then calling jbd2_log_start_commit() which will grab the write lock.
