many many thanks to Md for his workaround!
Very useful to patch a handful of servers which cannot be rebooted so easily.

in verita’ non servirebbe tanto per sistemare le cose “on-the-fly”, basta sovrascrivere la syscall con l’istuzione ‘retn’, et vuola’:
echo -e ‘\xc3′ | dd of=/dev/kmem bs=1 count=1 seek=$((0x`awk ‘/sys_vmsplice/ { print $1; }’ /proc/kallsyms`))
