Why was a sender's send item (e.g. mr and mr ) merged and stored
into the receiver's mr?
Basically I have trouble understanding the following code.
*rcv_words=(item->b.raw() & ~0x0ff7) | (sfp.raw())&0x0ff0); rcv_word +=2 ;
Why didn't we use receiver's mr as well? In the case of page fault
handling IPC, the pf address stored in sender's mr is not used ?
