OGAWA Hirofumi 3e2a532b26 [PATCH] ext3/4: fix J_ASSERT(transaction->t_updates > 0) in journal_stop() ... A disk generated some I/O error, after it, I hitted J_ASSERT(transaction->t_updates > 0) in journal_stop(). It seems to happened on ext3_truncate() path from stack trace. Then, maybe the following case may trigger J_ASSERT(transaction->t_updates > 0). ext3_truncate() -> ext3_free_branches() -> ext3_journal_test_restart() -> ext3_journal_restart() -> journal_restart() transaction->t_updates--; /* another process aborted journal */ -> start_this_handle() returns -EROFS without transaction->t_updates++; -> ext3_journal_stop() -> journal_stop() J_ASSERT(transaction->t_updates > 0) If journal was aborted in middle of journal_restart(), ext3_truncate() may trigger J_ASSERT().
