2.2 did not use hash tables, holding special single list for /proc.
If I understand correctly it was removed because added more data/work and new point of synchronization for main path being useful only for /proc. The approach would be justified, if you had 100000 sockets. In this case both approaches are equally slow. :-) But for 1000 sockets hash table of 100000 entries is sort of overscaled.

To fix --- no. To make differently --- yes.
Well, actually, if you are interested drop me a not I can pack for you some my old work on this. It is fully functional, but api is still dirty. It requires some patching kernel, unfortunately.
