Thus\nthe compile warning occurs.\n\nThought about changing the jbd2_journal_enable_debug data type back to\nint, but can\u0027t, because the jbd2-debug is moved to debug fs, where\ncalling debugfs_create_u8() to create the debugfs entry needs the value\nto be u8 type.\n\nEven if we changed the data type back to int, the code is still buggy,\nkernel should not print jbd2 debug message if the\njbd2_journal_enable_debug is set to 0. But this is not the case.\n\nThe fix is change the level of debugging to 1.
