Hi Andi,
I appear to have misread d_find_alias(). It would seem that the only way
to ensure that a mountpoint won't be found is to remove it altogether
from the inode->i_dentry list. AFAICS that should be largely harmless
since the nfs sb->s_root is never visible to users, and is never part of
a dentry tree.
Cheers
Trond
