FWIW, searching for graft_tree on arjan's site:
#12419:
negative dentry path->dentry
#17367:
ditto
#17463:
ditto
#13042:
probably the same (is that earlier oops you've mentioned?)
#18932:
WTF is that one doing there? (graft_tree is never mentioned in it)

Nuts... I really don't see how that could happen, unless it's NFS
revalidation playing silly buggers with dentries and ->d_revalidate()
there ends up turning dentry passed to it into negative one...

Where does the mountpoint in question live and what gets passed to
sys_mount()?
