However as far as I can tell the code has this limitation
deliberately for simplicity.
Getting the string side of this fixed even by itself is
worthwhile, although it might be worth teach people
about sys_uname and /bin/uname. It seems is the biggest thing
people look at /proc/sys/ for...
I come across this very issue when I discovered another bug,
using un-initialized pipefs structures during early hotplug
calls. I know about /bin/uname, but it requires a pipe, so
wont work. Obvious alternative is /proc/sys/version, which
is alot faster too (no fork+exec overhead).
