hi
I  have  attach a disk onto the vm
and now I try to understand the code relative to blk-attach
it seems like that device_creat()->createdevice()->addStoreEntries() 
,add store entry into xenstore , then backend and frontend will watch 
and do several related  work  to real add-device in backend and 
frontend  ,is it  right?  and  xenstore have watches to check the 
related entry ,is it right?
I am confused  ,which code or function to the real adding work, I guess 
it is the watches do it ,but I cannot find that fucntions

could you help me
Thanks in advance
