cvs commit: src/sys/sys aio.h signal.h signalvar.h src/sys/kern syscalls.master vfs_aio.c

[David Xu]

Existing binary code needn't be recompiled, it should work as before.
if an AIO syscall needs sigevent structure, it already has a new syscall
number, and old syscalls will think passed sigevent is an osigevent.
I am open for adding pad fields to aiocb and sigevent, how many padding
do you want to add, give some diffs for us ? :-)
