The following commit has been merged in the master branch: commit 5a5b9b8a06e3160b6ea80d87cad511538ca5357f Author: Ken Helias <kenhelias(a)firemail.de> Date: Fri Jun 13 10:57:53 2014 +1000 list: fix order of arguments for hlist_add_after(_rcu) All other add functions for lists have the new item as first argument and the position where it is added as second argument. This was changed for no good reason in this function and makes using it unnecessary confusing. The name was changed to hlist_add_behind() to cause unconverted code to generate a compile error instead of using the wrong parameter order.
