In a sense, yes.

Yeah, by small amount but also reduces memory usage quite a bit. For this case, I think dynamic allocation is actually the right thing to do.
Extending the first chunk size shouldn't be difficult on ia64 but other than this, there still is a lot of room left with the current 64k limit, so I think we should be safe for a while. BTW, I also am curious how lockdep has been coping with the limit.
Thanks.
