can't find memhook link

[XCloudAI]

In below UCX/wiki page
https://github.com/openucx/ucx/wiki/Malloc-hooks
it gives the link page of valgrind malloc hook code.
http://code.google.com/p/valgrind-variant/source/browse/trunk/valgrind/coregrind/m_replacemalloc/vg_replace_malloc.c#1175
However, the link seems not usable.
Could the community update the right link? Or tell what right is needed to see the code?
