I need to clean up some comments in the code. The other thing that I
want to do is to introduce read_seqlock/read_sequnlock() primitives that
do the locking without incrementing the sequence number. Then all the
name lookup and translation code can use the new primitives as they
don't change any of the protected structures. This will prevent one
sequence number check failure from cascading into a series of failures
because of the sequence number change. I will have a patch ready by
tomorrow morning.

Regards,
Longman
