PatchSet 6208 
Date: 2007/11/29 20:49:25
Author: rousskov
Branch: async-calls
Tag: (none) 
Log:
Added comm_read() that accepts AsyncCall. It is used by delayed reads now.
Eventually, all CNCB-, IOCB-, and IOACB-accepting comm_ functions will be
replaced by functions accepting AsyncCalls.

Removed unused IOFCB, IOWCB, and CWCB.
