Not sure. NFSv3 appears to be fixable, the only context is the UID,
which happens to be stored in the inode as well. NFSv4 and cifs could
be worse, I didn't look closely yet. smbfs accesses the dentry, which
has similar effects, but should be fixable as well.
Do you know of any impossible cases?

My second remark is that our intellectual powers are rather geared to
master static relations and that our powers to visualize processes
evolving in time are relatively poorly developed.
