Linux does have a specialized "raid10" class if you use md. See the manpage and other documentation for mdadm and of course double-check the device names you want, but this is what I have done in the past:
# create the array
mdadm -C /dev/md2 -l 10 -c 128 -n 4 /dev/sd[c-f]
# add it to the config
mdadm --examine --scan | grep md2 >> /etc/mdadm.conf
