Provided that those are proper primitives to start with...  I don't like
it - most of ->d_lock uses are _not_ related to ->d_seq, to start with
and then we get an interesting mix of functions that do and do not assume
the lock already taken, etc.

Could you describe RT patch problems in more details?  I really don't like
this solution - interface is overcomplicated and doesn't fit well...
