hi
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 there is somekind watches which  do it ,but I cannot find that 
fucntions

I am confused about it

could you help me
Thanks in advance
