Philip Homburg 1d7d5aa629 dev_close needs the filp number for asynch I/O, dev_io gets suspend_reopen 
flag to suspend a process until the filedescriptor is re-opened. Added 
dev_reopen, asyn_io, suspended_ep, reopen_reply, asynsend, diag_repl, 
close_filp, close_reply, unpause, select_reply1, select_reply2.
