[PATCH v11 01/19] dyndbg: add _DPRINTK_FLAGS_ENABLED

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Distinguish the condition: _DPRINTK_FLAGS_ENABLED from the bit:
_DPRINTK_FLAGS_PRINT, in preparation to add _DPRINTK_FLAGS_TRACE next.
Also add a 'K' to get _DPRINTK_FLAGS_PRINTK, to insure is not used
elsewhere with a stale meaning.
