Sorry I meant flags as an alias of "the 64bits currently occupied by the bitfield". Perhaps the name choice was not very good. "flags_bitfield" ? So the tool would only need to know that, not every bit. In theory it could be also generalized as a byte offset to perf_event, but that may be overengineered. -Andi -- ak@xxxxxxxxxxxxxxx -- Speaking for myself only. -- To unsubscribe from this list: send the line "unsubscribe trinity" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
