In this\ncase, the jbd2_might_wait_for_commit macro locks jbd2_handle in the\njbd2_journal_stop function while i_data_sem is locked. This triggers\nlockdep because the jbd2_journal_start function might also lock the same\njbd2_handle simultaneously.\n\nFound by Linux Verification Center (linuxtesting.org) with syzkaller.\n\nRule:
