What does RFO Hit and a RFO Miss denote?

Hi,

I am a little confused about what RFO hit and RFO Miss mean. I guess I know a bit about RFO hit, it signifies that if there is a write miss then a request for ownership is issued and the block is then put in exclusive mode for the core that issued the RFO. I dont know if this is right but that is what I have been able to find till now.

Now assuming that RFO hit is what I defined it to be, I believe the RFO miss should be the case in which the block might be in exclusive state in some other core and there is a write lock on it, ie the other core is currently write on that block and thus RFO is not successful(or RFO is a miss).

Please let me know if I am correct or not. Thank You.
