 A bit late in the game but for information:  Since r309108,in
stable-10 you are getting the INFO_RLOCK instead of the INFO_WLOCK like
in stable-11 and HEAD:

https://svnweb.freebsd.org/base?view=revision&revision=309108

 In summary the same TCP INP_INFO lock logic is used in stable-10, 11
and HEAD which simplify MFC if needed.

 My 2 cents.
