The reason for the special function, was not to provide a non-blocking

to transfer complex structures over it, it becomes hell. How do you
cleanly compat over a f_op->read callback for example?

Make it a netlink socket and fetch your structures using recvmsg().
siginfo_t belongs in ancillary data.

The UNIX philosophy is "everything's a file".  The Berkeley philosophy
is "everything's a socket, except for files, which are feeble
mini-sockets".  I'd go with the Berkeley crowd here.
