Hi,
This patch fixes the 2nd argument of mknod syscall. The argument
should include a file type, i.e., S_IFCHR in this case, otherwise
created files will be regular files.
Thanks,

Wierd. I guess no one has anything that uses this becasue current
code is clearly useless / broken.

I think so unfortunately ;< Actually lxc does not work in my system
with cgroups enabled. lxc code probably remains some other bugs.

oops, I've found a bug in the previous patch. Please replace with
the following patch.
