git.openvz.org has all the patches, but it's not easy to look through
this list as it is quite big.
We try to add all the patches which fall in the following categories:
- security
- bugs faced by OVZ users
- bugs we found and fixed ourself.

The patch is question was found & fixed by Alexey Dobriyan - one of our developers,
so the fix is here.

Thanks,
Kirill
