I am trying to use the INIT_WORK_ONSTACK() in my code, then I found in some places Calling destroy_work_on_stack() is missed. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

[PATCH 2/3] xfs: Calling destroy_work_on_stack() to pair with INIT_WORK_ONSTACK()
In case CONFIG_DEBUG_OBJECTS_WORK is defined, it is needed to call destroy_work_on_stack() which frees the debug object to pair with INIT_WORK_ONSTACK().
