        But is there any _bh change that is needed? There are so
many _bh changes but I don't see one that is needed. If I understand
correctly Lionel Bringuier, he never tried the plain IPVS, he patched
it and makes some calls from user space? This is my understanding
but I don't know what is the case. IMO, the caller should use the
local_bh_{enable,disable} calls, not IPVS. I don't remember for such
problems on SMP and I don't see them in the sources. Am I missing
something?
